Perhaps this answers a few questions. And I think I want a larger time constant, so I'll be swapping 1uF dipped ceramic caps into the design.

LEDs + superglue + Plexiglas + properly placed paint = RGB edge-lit waveguide pop-culture. Total internal reflection is a nifty arts & crafts tool.
The 'on' photos were made under the same lighting as the first photo, but modern 'superbright' LEDs are, in a word, 'superbright' and they completely blew out the camera even in the face of a direct overhead halogen floodlight. Amazing what 30mA gets you these days.

Some black walnut, acrylic scrap, a font, and Camilla's scroll saw lurking provocatively in the background.

....also a shipment from my very favorite Chinese LED vendor (ie, the only one I've found that seems to do actual QA, unit testing, and binning)....

A 4v 40maH rechargable LiIon coin battery, matched 1 sq inch solar cell and diode preassembled to charge when illuminated. Hmm, a small, self-regenerating power supply for $1.50....
Now, what fun could I possibly have with these?
