i was looking at this the other day... pretty cool...

anyway. for my apartment it would be pretty cool if i could get a scrolling marquee (LED? whatelse?) that would display sports score updates or whatever. Do they sell ones that you can hook up via USB? What's the cheapest way to do it?

buy a bunch of 5x7 LED matrices, some shift register / latch / drivers (like a 74HC595), a microcontroller with USB support (PIC 18Fx550) and then write software for the microcontroller and the computer. 😛
 
I always thought it would be cool to put something up like that in the back of a car somewhere so you could write messages to the person behind you ("pass me", "you suck at driving", etc).

🙂 That was the first thought I had too, though embellished with a on-the-steering-wheel keyboard for customizability 😀

I'm pretty sure it's illegal to have flashing lights in your car unless you're emergency personnell.

Might be a state thing though...
