Cool! Great work! Maybe in your next revision you could include IR comms - it would be nice if everyone in proximity had a similar glyph displayed....and then when you walk over to a new group, your glyph slowly changes. :-D

Anyway, regarding the visibility of the LEDs on a white background, a solution would be to cover the display in red cellophane paper. That will really make the LEDs stand out.

Shows what can be achieved when using 12 8x8 displays.
I have received a few bicolour 8x8 3mm displays, Still playing around with them. I suppose eventually I want to have a relatively large LED marquee. I suppose we shall see how it develops over time. :D
