another apparently undocumentable installation just about complete. opens Jan. 15th @ Conner Contemporary.
My first test with the pan-tilt servo unit.
Next up is finding a way to power and control a small fan attached to the end of it and finding a way to control a minimum of 5, but preferably X, more from one Arduino, I've found some links that look promising.
Starfield is an installation where a swing is used to create a large interactive starry sky.
With a Kinect installed behind the swing and a video projector, the software creates a galaxy of stars in which the user wanders with the rhythm of his swing.
Created with openFrameworks, the application allows to configure almost any type of swing.
With anaglyph glasses, a 3D mode gives an even more immerse experience.

The three artworks are Masks from Joel Gethin Lewis, which augments and adds to captured video of a viewer, using generative Baroque art inspired masks. Delicate Boundaries from Chris Sugrue which imagines a space in which the worlds inside our digital devices can move into the physical world. Small bugs made of light, crawl out of the computer screen onto the human bodies that make contact with them. Body Paint from Mehmet (Memo) Atken which explores how whole bodies can be used as brushes with which to paint a virtual canvas, using camera and projection technology.

In association with the first international OpenFrameworks World-Wide Developers Meeting, some of the world’s leading computational artist/developers will discuss their pioneering work at the intersection of arts and computer science.
During the week, the OpenFrameworks core development team is encamped at the STUDIO for Creative Inquiry to advance the next version of OpenFrameworks, a toolkit for new media education and creative coding. Each evening at 5pm, we will feature three or four short presentations by members of this team.
Presenters/Participants Include:
Zachary Lieberman / Theodore Watson / Arturo Castro / Mehmet Akten / Todd Vanderlin / Anton Marini / Damian Stewart / Kyle McDonald / Keith Pasko / Diederick Huijbers / Daito Manabe / Dan Wilcox / Jonathan Brodsky / Zach Gage

modelling the ycam library, solving for the projector intrinsics + extrinsics by selecting matching points on the model and from the projector's perspective.
Work in progress : playing around with the Holler logo with some boids algorithms & collision detection.
The goal is to gather different interactive sketches based on Holler logo in one application.
made with openFrameworks.
Testing an alternative rendering method for revealing depth information in point clouds, imitating photographic feel.

still a lot of design, pacing issues (especially in the last part) to work out, but here's a first prototype of my SMS to particle text system.

hellicar: That's really nice. Is the code up?
syedrezaali: Thanks @hellicar! The sketch code isn't going to be published, but check out ofxGenerative, I used the fluid field from there and a triangulated mesh to create the form, then linearly interpolated (via a color palette) the color based on the height
hellicar: Nice work
hellicar: @roxlu
I'm trying to come up with a good way to filter the results from a grid of points that you calculate Optical Flow on.
The results from a point go a bit crazy when there is not a good feature to track (empty space, no detail and just some camera noise) and gives odd results, so you need to filter out the stuff you don't want from the stuff you want.
(Finding good features to track seems to be pretty slow (finding corners and the like) so it's not something you want to do every frame, but this is worth looking into again.)
Previously I was trying to do this by comparing the points position against a motion image, the idea being that if something is moving, I'm probably interested in it. But of course that relies on getting a good motion image to use, which can be a bit hard under the best of conditions (if a crowd is in front of the camera for instance), under low light conditions it gets even harder, while optical flow actually still works rather well.
Here I'm trying to do it by comparing the direction vectors with the neighbouring ones and turning off points that don't have a lot of similar neighbours.
Simple stuff really, but it wasn't working very well when I tried it the last time, so here I've resorted to drawing the number of similar neighbours and the angle of the vector, taking a screenshot and having a look in Photoshop.
Good sanity check, but I should have spent more time looking at the code as it was a pretty dumb indexing error in the end.
Update: This method worked really well in end, relatively dark environment and it stayed responsive. One problem is that if you move too fast it won't really do what you want, but people seemed to catch on easily enough, they were not the usual demographic (young people who could even take a fair stab at what algorithms the piece might be using) so that's encouraging. Not sure if it has to do with blur or what, perhaps running at 60 fps would help, but I didn't have a camera that could do it at hand.
