Jay-R got some REALLY nice spotted cards made up for CNY. He even tested them with water, heat, and cold to make sure they wouldn't leave marks on the windshields.
I got bored tonight, since I have no life. The pic is from an autocross last year with byron's wing/roof, and Devin's Red WRX. Here's the prototype I thought up:

I suppose you'd have to write member name on them with a white or silver sharpie.

I'd like to stress that this is a prototype--even if everyone loves it Devin and Byron still need to give me permission to use the pic, because they're in it. Let me know what you all think, and by all means, plop down your ideas too!
