Okay, it's probably worth mentioning at this point that the transparent toaster concept doesn't actually work yet - while the prototypes might be able to gently warm a slice of bread, further research investment is needed to get the glass to heat up enough to actually toast it.

Inventables is an ideas incubator that's working on some very interesting concepts and prototypes at the moment, including fold-out e-paper screens for portable devices, mega-fast mag-lev waterslides, and cartons of milk that change color when the milk goes off.
