this is my go at music visualisation with blender 2.70. there is nothing realtime here, this is animated and then rendered. this is still work in Progress.
the music is "i could never be a dancer" by yuksek.
for the blender users: i didnt bake any sound to an fcurve, for it woudnt have helped me achieve the effects i desired. i used a lot of Drivers, the wave modifier, custom controls and the action offset plugin to ease the all manual animation though. go here for the BA-wip-thread: blenderartists.org/forum/showthread.php?331769-wip-my-take-on-music-visualization
