What is ".detuned"

.detuned (spelled simply Detuned in Japan) is a demoscene project by the German demogroup .theprodukkt (also known as Farbrausch), released exclusively on the PlayStation 3. It was initially released on September 20, 2009 in Japan, and on October 15 in Europe and North America. It is the second demo released on the PS3 after Linger in Shadows.

.detuned features a man sitting in a chair surrounded by a psychedelic environment. The player can switch into various modes, and using the trigger buttons and right analogue stick, apply certain effects on the man, which e.g. make his head shrink or apply a post-processing filter on the visuals and music. The player is also able to load their own music in.
