You folks are bad for the sanity. You've gotten me thinking
about implementing a PDF417[1] reader. I've done some barcode
decoding stuff at work, but I've managed to avoid doing any
2-D stuff. Now I may not be able to resist.

[1] For those who may not be familiar with it, PDF417 is a standard
2-D barcode. It's something like a bunch of really short (vertically)
1-D barcodes stacked on top of each other. It's not the densest
thing in the world, but you could get a lot more on a piece of
paper than printing text to OCR later. Most FedEx Ground labels
have examples of this code. (UPS labels have a different 2-D
code called Maxicode.)
