$14 Mango Pitter - I have cut many a mango, and I wonder how well this would work. I am not one to complain, though. This would shave, I dunno, 5 minutes off the mango prep time? Yeah, it's just that cool.
Panoramic Camera Ball. Throw it up in the air, and when it reaches its peak, it takes a picture out of each of its 36 camera's, and you can go onto a computer to view the panoramic pictures. This would be so cool for dancing at a wedding reception!
