IR Light toaster

Toast bread with any image.  40×40 array of ir led, one per side.  Bluetooth, WiFi, USB, SD card for images.  Small panel to select image.

Power required should be similar to existing toaster.  1500w for 2slices of bread. Maybe less if it led arrays are more efficient.

IR LED array probably not feasible.

Do it like a printer?  Single hot point, back & forth, moving down each pass.  Or a bar style, multiple LEDs in line, one scan horiz or vert.  A thermal printer might be a good start.
