For decades, we’ve been using mundane input devices to control our computer. Any dullard can press a series of buttons labeled with the alphabet or a small plastic mound named after a rodent. With the Makey Makey Go, you can turn anything into an input device. This video showcases some of the things you can do with the USB dongle, including a doughnut space bar, banana piano, and a number of situational selfie devices. For $19 bucks, I’d consider investing in one and trying to create some of these crazy contraptions, but I lack the imagination to do anything crazy. What do you guys thing it should be used for?
