We're just going to throw some words at you, see what happens. Piano stairs! Pencil joystick! Play Doh gamepad! OK now we've got your attention, head over to the MaKey MaKey Kickstarter page and throw some money at MIT Media Lab graduates Jay Silver and Eric Rosembaum's cracking lo-fi DIY accessory.
MaKey MaKey is a DIY Arduino board (what else) that you can plug into your laptop or PC via USB and then alligator clip to just about anything else in the room as your input. That means programmes, applications and web pages can be tricked into thinking you're using a normal peripheral like a keyboard or mouse when really you're typing on Alphabet Soup.
Some of the zany videos and photos already posted include using bananas or even your stairs as piano keys, drawing joystick keys onto paper with pencil to play Pac-Man and cutting virtual wood by slicing a real life twig with a real life knife. If your chosen object doesn't conduct the electricity too well, you can always just spray it with water, rub it with bananas or copper tape.
You can pledge US$35 now to get a full kit, which doesn't need any software or advanced tinkering skills, and the project will be up on Kickstarter until June 12th. Now, where did we put our child-like imagination?
