==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.
