OMG, you were reading my mind! I have another idea which is to mount these strips in rows (maybe 6 rows??) and then use the array to draw things :) Perhaps even animated things :D like Pac-man chasing ghosts or snowflakes.
If these were built in some kind of waterproof board, they could even be left on the house year round. They could be used for Halloween, birthdays, Easter, whatever. Oooh and the guys favorite thing is you never have to take them down!!!
