There are several good reasons to buy your own Flying Pig - Fledermaus model.

First, it's great fun and makes a nifty desk toy. Also, it's a good, solid example of instructional design and graphic art. Finally, it's cheap and lets you experiment with the nify BitPass payment system.

That's a helluva bargain for less than a buck. What else are you gonna do, spend your money at the iTunes Music Store? (That would make me happy too, of course.)
