Easily the coolest thing I've seen today(and I just finished doing some Quickbooks integration work so the bar is real high* )
I can picture this as a physical building block type toy where you plug the pieces in to a powered base and the results pump to speakers(or an audio out).
Would be great for annoying parents, and the spinning lasers would be awesome for optometrists!
* That was sarcasm, but the "coolest thing" statement was 100% honest
