Warpstock 2013 hats, shirts, mugs, and other swag

As an example, this great coffee mug is for sale at only $12.09, highlighting this beautiful artwork.
Larger mugs, teddy bears, tote bags, refrigerator magnets (almost computer-safe, now that floppy disks have become antiques!), and a whole host of other things you might not have even realized, and don't forget the essential mousepad (even optical mice need smooth, non-reflective surfaces for optimum performance) and BBQ apron.
