Seems cool, but not better than Snap Circuits.

Agreed. Snap circuits is great. The mechanics are easy enough that my three year old can put together simple circuits.

Note: unsuitable for air travel.

Heh, yep, I'd love to see what the TSA would make of a lump of plasticine with embedded electronics.

I'll watch the video later today, but I wonder if this might not make for some truly _excellent_ summer projects for my 7-year-old daughter, a self-described "geek girl".
