Water Powered Calculator

If you're one of those nerds that just bought a new calculator since somebody threw yours away into a pool or beach or something with water then you'll want this calculator. The Water Powered Calculator uses three alloys that create electricity when water is put into them. You have to fill up the batteries every two months though. You can buy one here:

Takumi Crash Calculator

Here's another weird product from Japan. This calculator is called the Takumi Crash calculator. Unlike most calculators this one will just crash whenever it feels like it. I don't know why they decided to make the keys look like Tetris though. Unfortunately you can't buy it because the site (http://www.idea-frames.us/) that sells it is under maintenance.
