Oh, this is just lovely. We saw on Offworld that following on from the Diablo III: The Rainbow Islands furore last year, the Blizzard chaps are snickering behind the hand. With doctored screens and their own internal T-shirts (Grab via MTV). Which is the design at the top. But, most relevantly, you can now order for your very-ownsome via Nerdy-Ts.
As a note to developers, I'd be all over a Rainbow Islands Versus Diablo game. Just for the record.
EDIT: Just in comments thread, there's a 20% off code - "NerdyFriend2009" - which works until Monday.
