@CodeSmith,
It looks pretty good, actually.
Yeah.. I can see how a RTS game could benefit from this, not to mention 3D gfx and stuff.. (Offcourse if the update speed of the leds is fast enough)
Unfortunately, it's a bit pricey (I think the guys selling them said something about $2000 for the fancier, 8-colour model).
Well, with most tech, it will get cheaper I hope.. I'll start checking Ebay :-D
