Today I investigated the MySpace: CircuitBent group. Nothing that really beats Yahoo: Benders or the LiveJournal Groups. Basically a handful of artists and a large group of people with silly photos. Through some browsing I stumbled on the profile of the chiptune artist Chesterfield showing some bends and a few Gameboy Mods. He so happens to be promoting for the Bend++ Festival ( Official Blog Link?) which just started in Japan!
Chesterfield’s website is full of links, audio files, and videos ( specifically this manic Speak glitching video ) so poke around at http://bending.hp.infoseek.co.jp/
