Check out this rather unique concept of a toaster known as the Smile Cooking Toaster – it comes in a transparent form factor, boasting an electric-heating nano-membrane as well as a variety of smiley faces that you can choose to have appear on your bread once it is ready to eat. The see-through material used allows you to see the bread being toasted as well as the smiley appearing gradually with time, helping introduce a new way to greet what could be a potentially depressing week at work.
