Audiosurf: Cirmix crossfade (HD)
I'm still in search for this album.
Also someone on Audiosurf forums got a little neat thingy for using animated GIF as a background for audiosurf. Also I'm in search for this album. I wanted to convert the video on http://www.conagusuri.com/cirmix.html into GIF, but found out that converting a 330MB video into a GIF was not really a good idea.
Did I mention that I want this album?
