i dreamed that heather was teaching me how to play ultimate
frisbee, except it was indoors, and once you got good you no
longer played it with a frisbee, but a blue requetball, which
would seem to float in the air becuase it would spin so fast.

and i thought boy, if i wrote a paper on the aerodynamic flow
around the ball, i could be famous.

later, we switched to a square (or rather cube) "ball"
