I picked up a sketchpad and a 64-pack of colored pencils at a local hobby store to do so random drawing.
I'm no artist and I can't draw. (My artistic abilities are show-cased on the yellow arrow here). However, I do get a kick out of doing various math equations. The drawing wasn't working, and so I almost started using the colored pencils and paper to start deriving various math formulas. It would have been the most colorful derivation of the quadratic equation yet!
I hear similar stories of people "creatively" using our products. Using excel as a wordprocessor (in cell A1), etc.
