My aim was to create circular shapes out of manipulated linear fibres. I investigated dipping fibres in wax, tearing, combining and wrapping fibres to investigate different qualities before wrapping them into circular shapes. I used these shapes to create design ideas on the body and also on the face. The resulting effects reminded me of black holes and whirlpools. The colour schemes created are derived from the pieces of fabric I have utilised. I then decided to investigate this wrapping in 3D and experimented with tights on a model’s head. The effect was quite dark and reminiscent of bandaging.
Filaments of Active Galaxy NGC 1275
What keeps these filaments attached to this galaxy? The filaments persist in NGC 1275 even though the turmoil of galactic collisions should destroy them. First, active galaxy NGC 1275 is the central, dominant member of the large and relatively nearby Perseus Cluster of Galaxies. Wild-looking at visible wavelengths, the active galaxy is also a prodigious source of x-rays and radio emission. NGC 1275 accretes matter as entire galaxies fall into it, ultimately feeding a supermassive black hole at the galaxy's core. This composite image, recreated from archival Hubble Space Telescope data, highlights the resulting galactic debris and filaments of glowing gas, some up to 20,000 light-years long. Observations indicate that the structures, pushed out from the galaxy's center by the black hole's activity, are held together by magnetic fields. Also known as Perseus A, NGC 1275 spans over 100,000 light years and lies about 230 million light years away.

At one time, it was the lightbulbs that had filaments.
Used in week 41 - Patterns - a Compositionally Challenge group challenge.
This is a miniscule segment of a tungsten filament used for aluminizing mirrors. Unfortunately it is also a failure. This is what a filament looks like when the firing process is halted halfway through the job.
In use, the filaments are loaded with high purity aluminum, and are then heated exactly like an incandescent light bulb. The aluminum melts, and then wicks into the gaps between the individual tungsten wires in the filament. The temperature is then increased to the point where the aluminum vaporizes. Aluminum molecules then radiate from the filament in a ballistic trajectory, and stick to whatever they hit. If that happens to be a chunk of highly figured and polished glass, the result is a mirror.
After firing the filament is no longer pure tungsten, but winds up being a bizarre tungsten/aluminum alloy. In this case the process was halted quite early, so there's no telling what the composition of the filament itself is. The crystals on the outer surface are almost certainly crystalline aluminum.

Received two spools of 1.75mm NinjaFlex filament in black and white from fennel drives this morning. My Prusa won't be finished for a few weeks so I have nothing to extrude it, but I am excited to try out this new material.
This shot was taken by breaking a light bulb and photographing the filament as it burns in the air. Normally bulbs are in a to vacuum prevent the filament from burning. By removing the glass and shooting several shots in quick succession I am able to capture this image.
Edited SDO image (one of the most famous it has taken) of a huge filament from the sun, several years ago.

It also contained two filament spools:
• White ABS 1.75
• Translucent Blue PLA 1.75
Spools are smaller than usual:

Another watery abstract cavern image made with ACDSee photomanipulation software (I believe it's free to try for 30 days via the amazing ZDNet.com).
Two double-green-gelled flashes (580EX (thanks, Alan!) and 580EXII) @ 1/16 to left and right with baffles to keep the background dark, triggered via ST-E2.
The significant change compared to previous efforts was dumping the softbox and using the flash direct, which allows winding back the flash power a bit.
