Found on Flickr user Tableauvivant’s page, this above photo shows the musical components of a Hallmark musical greeting card. I must say, this is quite surprising. I was sent a few musical cards back in May and when I took them apart, I found a tiny PCB with a piezo speaker and some other circuitry. This appears to be a speaker with gears and cardboard. Very cool. I wonder how you could hack this thing to make it play different tunes.

Kick ass pedal powered Panzers are fighting the good fight. The second annual Kensington Kinetic Sculpture Derby inspired a group of guys to construct a human powered Panzer Kampwagen III in 11 days for the purpose of crashing the party. By the time they were finished the tank, they were too tired to crash any party, so they just spent the night in the tank.
If you’re in the Philadelphia area, you can visit the tank where it is now being displayed as public art on the west side of Frankford Ave, just north of Norris St. This monstrous skeleton of gears and steel will be the first place you’ll want to go when the bombs drop.
These Bonsai Gear Clocks are named after their brilliantly intuitive design. A set of clock gears meshed together to resemble a bonsai tree. Made with ABS plastic gears, metal stem and a wooden base, the Bonsai Gear Clock runs on 2x D batteries (yeah, the big ones).
The very slick design is a beautiful mix of technological invention and the beauty of nature. It can be yours for $90. — Andrew Dobrow
