I wonder how much it would take to mass produce these and sell as programming toys/tools? I'd buy one.

PS: if someone else would be serious about pursuing this, i'd love to be a part of it

Great idea! To be honest though I lean more towards toughening them and selling as nightclub lights. Even the smallest of places spends megabucks on their lighting rigs, and this would be a toy that every bored sound tech would love to play with :)

Edit: I'm not the only one to have thought about this: http://www.youtube.com/watch?v=_cLLyfop3QI

Edit2: This company appears to be offering them for sale in sizes up to 32x32x32: http://www.seekway.com.cn/e/ledsys9.htm

Amazing video here!

Before you wonder about the 'crappy resolution' do the math, 32x32x32 is 32768 individual leds. The video appears to be of a 32x32x16 array.

Those look to be RGB as well. So that is 4 connections per LED (red, green, blue, ground).

Price for this one is $400. A lot more expensive than I thought.

Wire up an interface so you can control it from a lights desk and you could charge 5 or 6 times that.

If you were truly mass producing them, it'd be cheaper to get them made in China/India, and cooler if you could do it with smaller leds in a smaller cube.

Thinkgeek sells a 4x4x4 version for $80: http://www.thinkgeek.com/interests/techies/d71d/

Doesn’t look programmable, though? That would make it next to worthless for me, unless it’s possible to hack it easily (not that I would be able to do that).

i have this one http://www.seeedstudio.com/depot/rainbow-cube-kit-rgb-4x4x4-...

I've put it together but haven't had the time to test it out. It also requires one of these: http://www.seeedstudio.com/depot/rainbowduino-led-driver-pla...

So it is most definitely programmable, It was a bitch to solder together though.
