ah yes,
here's my next idea:
especially on multimedia programs (video players and so on) a control which simulates a virtual curtain like in theatre would be extra extra cool.
I'd propose following properties:
curtain colour
curtain style (old fashioned with ruffles and golden ropes, modern - without those things)
open/close speed
open/close direction (left/right, up/down)
stay visible - controls if curtain is visible if it's opened (or moves completely out of the picture)
maybe even a property for very little movement in random timespans to make look it more realistic
Methods:
open, close
