This is a video of the Star Wars Imperial March played on a 3 1/2" disk (the 5 1/4" floppy's rigid little sister). It's just as awesome as you thought it would be. Unless you thought it wouldn't be awesome, in which case you're wrong. Just like I was when we were playing along with Jeopardy at the bar last night. Seriously, never wager your left nut on a Daily Double.
Two more videos after the jump -- a flatbed scanner playing Fur Elise, and one playing Ode to Joy.
Thanks Flogag, let's start a band with nothing but computer components. We'll be rich!
