I've known about this for a few weeks but it looks like it has finally gone live. Inkwellideas produced dungeonmorph dice with Dyson Logos, Matt Jackson, and others. I even got a few faces on the dice.
It is pretty cool to be able to say "Some of my work has been sold on Think Geek!"
full disclosure: I get a commision when you buy a set - so go buy a set!
