Yes,..Amercian designer Victor Vetterlein has made "Bite Me", an edible desk lamp. Bite Me has been designed and made using a material which is derived from gelatin which allows the user to consume the piece when it is no longer useful.
Bite Me is available in four different flavours, orange, cherry, blueberry and apple.
The gelatin used is low in sodium and very low in saturated fat as well as cholesterol.It is also a good source of vitamin E, vitamin K, pantothenic acid, zinc and copper, and a very good source of folic acid, calcium, iron, manganese, potassium and magnesium.
So not only are you experiencing the unique interection with this design piece, its also good for your health :)
