"Dripping sounds" by Federico Muelas.
A sort of silver screen about one meter in diameter, onto which light is projected through a little water tank. Ink drops fall into it, creating a smoke like pattern. The projected image is used to create different sounds, triggered by light sensors on the silver screen ... .
Fascinating, dreamy, and creating a strange mood in the room.

Sensor dust before cleaning, only the two very obvious spots (dot lower right and hair lower left) showed up at other apetures in blue skies and such. To make the sensor dust more clear I upped contrast a lot.
After years of putting up with dust spots, which show up as ugly grey smudges on photos of nice blue skies, I cleaned the sensor on my Nikon D70. It took quite a few goes as you can see. Each of the photos here is an out-of-focus picture of a blank white computer screen which has then had its contrast increased hugely (by doing "auto contrast" on it) to make the dust spots show up better. The little round spots are dust. The other variations and the larger, slightly dark areas are tiny variations in intensity of the LCD computer monitor which have been exaggerated by the 'auto contrast" step.

What kinds of Touch Panels Are You Looking for?
A touch panel is one of the kinds of computer display screens, which can also be called an input device. Due to the sensitivity to the pressure of the touch panel sensor, users interact with the computer by touching the objects on the screen.
Three types of touch screens are listed below:
Resistive Touch Screen:
A resistive touch screen panel is a sensor that is basically a film-plus-glass structure that converts the physical position of a touchpoint (X, Y) in a rectangular area into a voltage representing an X coordinate and a Y coordinate. Resistive touch screen panels are generally more affordable but provide only 75% clarity and the layer may be damaged by sharp objects. Resistive touch screens are immune to external elements such as dust or water.
Surface Wave Touch Screen:
Surface wave technology integrates acoustics, electronics, and semiconductors into new technology. They have the advantages of small size, flexible design, mature technology, good consistency, and reliability. Surface wave technology uses ultrasonic waves that pass over the touch screen panel. Surface wave touch screen panels are the most advanced one of the three types of screen touch panels, but they can be damaged by external elements.
Capacitive Touch Screen:
The resistive touch screen panel is constructed by placing a transparent thin-film conductor layer on the touch panel glass and adding a protective glass to the conductor layer. This double glass design completely protects the conductor layer and the inductor. With the rise of smartphones and tablets, the capacitive touch screen panel market has been developing rapidly.
Touch Points of the Touch Panel
Single, or Dual/Multi-Touch?
Single-touch interaction is capable of, at a lower price, realizing all the applications' goals. Gesture interaction, including, flick, slide and knead, requires dual/multiple support. Select the alternative to continue.
Single Touch Point Only
Aiming at supporting single-touch input, resistance touch screen is designed. Various types of materials are available because there is no limitation of the materials which are used for input. Besides, resistance touch screens have the advantages of mature technology, stability, high-cost competitiveness, and excellent detection accuracy.
The advantage of single-touch is that the device design space is optimized, especially for small devices, because it can "install" screens and buttons in the same area at the same time; second, because the buttons can be bound to any application in the operating system, So the "buttons" used by the device can reach an unlimited number.
Multiple Touch Point Support
The user's two hands have ten fingers, and when the users interact with each other, more fingers appear on the screen. This is the origin of the multi-touch concept of recognizing the position of a finger, which enables manipulation of more than two fingers. Projected capacitive touch screens support single or multiple touchpoints. It allows for the interaction of gestures. One point to mention is that no part of the resistive multi touch screen physically will move at detection, and it makes the touch experience smoother and lighter (just like smart-phone).
How Does Touch Panel work?
Different people work differently. So it is with different types of touch screens. Some can easily detect and distinguish multiple keys at the same time. However, some others can only sense one finger at a time. If you try to press two places at the same time on this type of screen touch panel, the screens will be rather confused. Here are some of the main technologies listed below:
Resistive Touch Panel
Resistive touch screen panel (the most popular technology recently) works a bit like "transparent keyboards" overlaid on top of the screen. The flexible upper layer of conductive polyester plastic is bonded to the rigid underlayer of conductive glass and separated by an insulating film. When you press the screen, you can force the polyester to touch the glass and complete the circuit - just like pressing a key on the keyboard. The chip inside the screen shows the coordinates of the location you touched.
When you press a resistive touch screen panel, you push two conducting layers together so they make contact, a bit like an ordinary computer keyboard.
Capacitive Touch Panel
The capacitive touch screen panel needs to achieve multi-touch, relying on the electrodes to increase the mutual capacitance. Simply put, the capacitive resistive touch screen is divided into blocks. Each set of mutual capacitance modules is working independently in each area, so the capacitive screen can be independent. Detecting the touch situation of each area, and after processing, simply implement multi-touch. When you bring your finger up to the screen, you alter the electrical field by a certain amount that varies according to where your hand is.
Touch Panel Solutions
We provide resistive and capacitive touch screen solutions to you.
In a capacitive touchscreen, the whole screen is like a capacitor. When you bring your finger up close, you affect the electric field that exists between the inner and outer glass.

My Baroesque Barometric Skirt reflects environmental data, plus my personal temperature - it's a reflection of the self within the bigger picture. What I mean by this is that how I pass through and interact with the ambient environment interests me. To visualise this passage I have created a skirt that uses sensors to glean environmental data in the form of a barometric sensor board, its data more commonly familiar to those who track and predict weather. To the viewer of the skirt, they will see colours changing in real time on four rays of RGB strip, one for each sensor reading.
This is how I’ve put together the electronics inside the skirt: the aforementioned barometric sensor board protrudes from the skirt and gleans the ambient temperature ( Celcius C) around it, the other sensors on the board collect data and via algorithms in the code work out the altitude (meters m) and pressure (Pascal Pa). I’ve used a Shrimp kit, which is similar to the Arduino Uno, that comes as a bag of components and soldered it onto stripboard. Another temperature sensor, measuring my temperature sits on this stripboard, Four lengths of RGB LED strip radiate from the Shrimp circuit and both the stripboard circuit and the RGB LED strip are sewn onto what I call an ‘apron’, which sits under the skirt and is detachable for washing purposes and also as I like to fashion my electronic circuits as interesting pieces to be viewed in their own right.
The code takes the readings from the sensors and runs an algorithm firstly to convert the data into Celcius, meters or Pascals, and then runs another to mix the colours appearing on each corresponding RGB LED strip. There are 7 colours I’ve set to pass through, the lowest reading being blue, followed by cyan, white, green, yellow, magenta and finally red for the highest reading in each sensor reading data band.
It took a months to create the skirt as there was so many iterations between experimenting with circuits around how to make my idea come to life and creating the skirt, testing paint on fabric, choosing a visual metaphor and style of the skirt, then making the skirt. Next finalising choice of the electronics, coding, prototyping, then transferring the circuit to stripboard. Finally soldering everything together and then debugging, testing, making changes to the code, before eventually putting the skirt and the electronics together.
The Baroesque Skirt’s weather artwork was inspired by the characters Amaterasu & Kabegami from the game Okami.

Sensor after I cleaned it. There are still a few spots around the edges, but those likely end up being cropped out anyway, so I'm satisfied with the results for now.
I wonder how well the Canon Rebel XTi sensor cleaning works in comparison. Getting out lint free cloths and swabs and locking up the mirror is a pain (and dangerous).
The unwelcome inhabitants on my sensor. I'm going to be buying a cleaning kit to eradicate these little fellows.

Fell behind on these. The EXIF on this shows it was taken on 01-Jun-2013 and adds a tiny bit more crud on the sensor from the last one. You'll have to look pretty hard to see the new spots, though.
Shutter actuations are at 5,065, so you don't have to go hunting the EXIF for it.

Image of my sensor just after a good cleaning (small spots are left, but it's not a problem for usual images). The darker parts on the corner are due to vignetting and not some kind of sensor dirt. This is perfectly OK.
To obtain such an image:
- Go to maximum aperture (f.22 or f.30)
- Adjust speed and take a white surface shot (long exposure is not a problem, if you move the camera when taking the image it avoid confusion between the white surface dirt and sensor dirt).
- Apply an auto-level on the shot, here is the result.

These diagrams are supposed to show why you need a small aperture when checking for dust on your sensor.
The vertical red line represents the sensor and the vertical grey line represents the AA filter. The black blob is a dust particle. The top diagram shows light coming in at a narrow angle, corresponding to use of a small aperture. The blue area shows the region that is in shadow at all angles, and since it reaches the sensor the resulting image will show a dark spot there.
The bottom diagram shows light coming in at wide angles corresponding to use of a large aperture. The green area shows the region that is in shadow at all angles. Since it does not reach the sensor the resulting image will not show a distinct spot from the dust particle. Some light can get around the dust particle. There will be an area of reduced brightness on the sensor, but it will not be as noticeable as it would be when the small aperture is used.
Agfamatic Sensor 100, Germany, 1971.
What must be the best, most minimalist case ever designed for a camera.
The Agfamatic 100 is a viewfinder camera for Pak-Film 126 cassettes. It has an Agfa Colorstar lens with fixed focus and fixed aperture. Two shutter speeds are selectable with the ring around the lens barrel, the scale showing a cloud and a sun symbol. The camera has a single stroke advance lever that advances the film, cocks the Parator shutter and turns the flash cube holder on which magicubes can be fired as flash. On the axis of the advance lever is the red "sensor", the shutter release button hidden under a round piece of red foil.

... This pic and others like it never made it to a final edit. HORRIBLE!!!
No, its' not what you think!!!
If you could see it very large, you would see just how much this photo resembles SMALL POX! This shot was taken back when not only was I a know-nothing, horrible photographer, but I was neglectful of cleaning my sensors because I didn't shoot at the ultra narrow apertures. The sky in this image LITERALLY is beyond repair.
It wasn't fair that my two good weather days in Yellowstone were cloudless, then my one day in Grand Teton was nearly a rain out.
