It's named after the Metalheart book by Andreas Lindholm (2001). Pioneered by design firms like the Attik, Brainreactor, Gmunk, etc. in the late 1990s, it peaked & became oversaturated by the early 2000s, then essentially vanished in the late 2000s, morphing into McBling (basically Design Student's Orgasm on TVTropes) vector graphics, and replaced by more hand-drawn Hipness Purgatory
