Thought I'd plug this news article that I saw the other day. Basically these two guys took an Apollo Geist figure, kitbashed it into a Utopia Dopant figure, and tried to sell it on Yahoo Auctions (yes, that still exists in Japan) when they got arrested for copyright infringement.
"The winning bid was around ¥270,000 (US$3,288), a tidy sum indeed."
