Fun with LEDs

I want to start messing with LEDs; I have two (similar) projects in mind. I want a strip of multi-colored LEDs to respond to music. And second, inspired in part by this thread, I'm interested in learning about turning sound-responsive LEDs into a costume. I imagine those two projects are pretty similar, other than needing a portable power supply for the latter, right? So, can anyone help me figure out what I should get to start with? [more inside]

Will my room look nice if I illuminate it with LED strips?

I have a large room that I would like to illuminate with LEDs. I'm thinking of putting a ledge around the the walls about 45 cm / 18 inches from the ceiling and laying LED strip lights along it, directed upwards so they bounce off the walls and ceiling (which are painted white). Would this look weird? Would it light the room adequately? I'd make the ledge with a groove in the top surface so that you can't see the LED lights from floor level. [more inside]

Help me whimsically prank some folks.

Where can I find some small, cheap flashing lights? It doesn't really matter what kind of light they are as long as they flash, a variety of colors would be nice but not necessary, the ability to turn them on and off is nice but not necessary, they shouldn't require a cumbersome power source but they don't need to last much longer than ten minutes, and I need to be able to obtain them by tomorrow (Saturday) in NYC.
