Head to http://www.cafepress.com/haskell for your holiday shopping. Thanks to Conal Elliott and Fritz Ruehr for their artwork. Conal's design was produced by Pan so this shirt is in fact powered by Haskell! I'll be glad to add more designs in the future. Once cafepress lets me put more than one design in a store I'll consolidate everything. Meanwhile, if you want to set up a separate store I can link it into haskell.org for you. John
