We've seen a NES crammed into a toaster and made functional before. And it was awesome. So of course the next logical step is giving the same treatment to an SNES.
Yes, the Super Nintoaster will let you play Chrono Trigger or Super Metroid from what appears to be a pop-up toaster. The heat generated by a toaster makes it impossible to still toast bread while you play, what with it melting the cartridges and everything, but I don't think you can hold that against such a great device.
