So, this exists: PlantPot's Finger Hoola, a simple arcade game where you do exactly what the title suggests! It's not code for nose picking or anything strange, you just place a finger on the screen and play a game of two dimensional hula hoop. Weird, right? Strangely fun, and with a nice ambient score and abstract backdrop to soothe your eyes and ears. Who knew drawing tiny little circles on the screen would translate into such a great game?
