How To Emulate An Electronic Rubiks Cube

This is not a "how to" this is just a video of you playing with a lit rubiks cube...

im finland tota onhan se hieno mutta ei kovin äänekä ;s! hieno on.

where can i buy this thing??

I fail to see how this is a good idea, Okay so I'm on a long road trip and I wanna play with my Rubiks cube oh guess what, half way through the game the batteries die on the thing. Sure its a neat trick, idea whatever you want to call it. Practical No. I just know when you go to pick up and play with the cube its going to have been sitting for so long the batteries are going to have died. In other words just a world of annoyance.

There's no how-to, but I guess this uses the same technique used to "read" from leds. Apparently leds can be used to detect light too, so if you flash em on and off quickly and reading them in between, you can track the fingers and make the cubes turn. Cool idea.

How to emulate? That's not showing you how to do anything.

That is probably the Coolest rubik's cube EVER!!! Too bad that wasn't around when I was a kid...

That's very, very cool. Quite impressive.

that how-to was full of FAIL.

so where's the "how-to"?
