This most unusual circuit board kit allows users to convert fresh fruit into a musical instrument. No, really...the MaKey MaKey is not an April's Fools product. You can actually order one and make yourself an alphabet-soup keyboard!
“The MaKey MaKey board requires no special tools, and is simple enough for children to use. But, also built in are additional capabilities – such as expanded keyboard ports and arduino compatibility – allowing users to invent even more elaborate devices as your experience grows.”
