I was looking for a peripheral that could make gaming with just one hand possible, and I stumbled over this video which seemed so cool that I thought I'd share it with you!
When you said "Banana Phone", I thought "Hamburger Phone". I bought one of those for my ex-gf after she fell in love with the one she saw watching "Juno". ^^
I'm really tempted to get one of these MaKey MaKey thingies though, not only for the person I had in mind, but also for myself. Such a useful toy!
