Brutal Legend video explores game world's art style

The latest Brütal Legend video has Art Director Lee Petty describing the style and artistic influences for the game's world. Most of it is interesting to those out there with an art degree, but we certainly got a giggle out of one of game's factions being inspired by 15th century art and "[Double Fine's] tremendous amount of research into the S&M scene." We wonder if those toys like "leather straps" and "ball gags" were brought into the office and purchased with the company credit card for "research" ... and whether Tim Shafer now keeps a dungeon for employee use?

... Hey, the game is M-rated, this is a perfectly appropriate question to ask. What?! Stop looking at us like that.
