Wow. Putting the vanishing points waaaay too close, say right at the edge of a vertically-oriented business card, makes for a weird effect. Reminds me of some background plates I've seen in comics.
Cityscape 5 got me to thinking about doing blocks of text in the same fashion, so I sacrificed another couple of business cards to the felt pen to try it out. I think it would look cool on a t-shirt.
