Art is important to Blizzard. The offices of the World of Warcraft developer, currently working on RTS sequel StarCraft II, are plastered with it. Vivid, colourful and extravagant concept art is hung everywhere. The offices even have a curator, part of whose job description is to ensure that huge floor-to-ceiling pieces are displayed around the campus. One such piece is in the canteen - a jolly painting of drinking dwarves by Samwise Didier.
