on chopping board
One is the Chop2Pot, a design which I have seen somewhere before. Basically you can use it as a chopping board (duh) and also when you fold it up, you can use it to pour stuff into the pot. I've never used it in a kitchen, but when I did a little hands-on, I found that the the board can somehow fold/flap backwards (not intentionally) and then all the contents will drop everywhere.
The other design is called Rinse&Chop. Again you can use it as a chopping board, also when you fold it up it doubles up as a colander/strainer. The folding is less complicated then origami, but neither is it very intuitive.
Innovative designs that can save on kitchen space and make cooking more convenient, but I am not really comfortable with the folds. Guess I'll stick to my block of wood.
