==Day 1 (2009-05-03)==
Cut aluminum channels with beveled ends to fit acrylic pane. Notched end of one channel to allow LED ribbon power cord to enter.
Adhered LED ribbon inside the four aluminum channels (arranged in a long line on the floor) and placed bumpers at regular intervals.
Lifted channels and place them around pane. This took a few tries because the bumpers would easily fall out. Maybe use some mild adhesive on the bumpers next time.
Milestone: After powering up LED ribbon, we were able to see bright fingertip blobs using an infrared sensitive webcam in a darkened room. Yeah!
Other data points:
* Apple iSight (both builtin and free-standing) must have infrared filters, since they cannot see blobs.
* "Etched Glass" window film will not make a good surface, since when attached smoothly and firmly, it disrupts internal reflection too much.
