As a few of us will be going to the Desktop Developer's Conference in a couple weeks, I put together some shirts on CafePress.

Some people have suggested I post about it on the developers' list, so I added some more products and here it is:

All the shirts are being sold at-cost (relative to Cafe Press' base price), so neither Inkscape nor I benefit financially from sale of the shirts. It's just something cool if you work on Inkscape and want one.
