This series represents some of the results of my efforts in response to my contact DB1of1 who asked for ideas to photograph an incandescent filament.
Rather than “treadmilling” like animal cell actin filaments, Staiger et al. find that plant cell actin dynamics rely on rapid polymerization followed by severing events (arrows). (JCB 184(2) TOC2)

This was harder than it looks! I had the light switch in one hand and the camera remote on the other. I tried to fire them at exactly the same time to catch the filament lighting up. It took me a hundred or so tries.

(Linz, November 24, 2010) Ars Electronica Center Linz is hosting its second LabDays event. The center of the action will be the laboratories—labs, for short—in the Main Gallery, where participants will be able to spend two amazing days experimenting, tinkering and playing under the watchful eyes of experts invited especially for the occasion. “Microcosmic” aptly describes everything attendees will encounter on these LabDays, which target all age groups, advanced users and newbies alike.

This is what the finished spooler / filament guide looks like. I am probably going to scrap it. It pulls filament fine and haven't had a failed print yet, but I don't like the angle it pulls the filament down at. It is basically going 90 degrees out from the bearings straight down into the extruder. The plastic is visibly discolored by this sharp angle. So I have two options, print a filament guide FOR my filament guide, or move the spool some where else.

Filaments are formed in magnetic loops that hold relatively cool, dense gas suspended above the surface of the Sun -
a small spotlight I have projects an image of the bulb's filaments on the wall when you remove the diffusing filter from the lense . The spotlight also has an iris which when closed a bit sharpens the image
