The 3D animation and music of this site is cool although it can be quite irritating to some people. Looks like this was created at least 2-4 years ago ( when 3D flash was much harder to implement )... Its actually a showcase managed by the electric rain... Another good showcase site of theirs is the illumination ( http://www.swift3d.com/illuminations/ )
