Bamboo iPhone speaker amplifies music with zero electricity
The iBamboo speaker makes use of the naturally resonant properties of bamboo to provide zero-electricity amplification for the iPhone 4. Yeah, you could get more gadgets to go with your gadget, but this is probably cooler — no wires, no energy use, and it adds as much Zen cool to your desk as a tiny portable waterfall (which would need to be plugged in anyway).
The inventor is looking for patrons on Kickstarter — he's already gotten enough backers for the project to be funded, but you can still pledge your support and secure yourself a spot as an early adopter. A $25 donation (probably about what they would cost on the market) gets you one of the first speakers off the assembly line, plus the warm pleasant feeling of backing a supercool project.
