Here is an interesting toaster concept designed by Sung Bae Chang called Scan Toaster that can burn anything to a slice of bread. Connecting the Scan Toaster to a PC via USB, it will download useful information that can be burnt.
Inside the toaster is a network of toasting “modules”, each heated by a hot wire. Each module can move by 30° and, once the user selects what they want on their toast – excluding a topping, of course – the modules align themselves and burn the appropriate content onto the bread.
This concept is one of the finalist of a design competition held by Electrolux.
