I decided none of the AudioSurf dock icons I had seen would cut it, so I made my own. Made a few quick observations about the "squid," then made my own in Maya and textured using Illustrator (the texture is extremely simple). I then finished the icon in Photoshop.
There are 512, 256, and 128 pixel PNGs and an ICO file with more sizes than you'll ever need to use including 256px, ready for Vista.
If you would like the squid minus the background, I have that available here.
You're absolutely correct, it's better than 99% of the icons for Audiosurf that I've found online. Also, you're the #1 Google result for "Audiosurf icon 256". Congratulations. +Fav
Created the "squid" in Maya, starting with the head, then created one arm using smoothed cubes arranged to make one of the arms. Pulled out the corners on the appropriate cubes, duplicated it 7 times and rotated each duplicate appropriately, then textured with a relatively simple blue/white pattern fitting the cubes and head appropriately. Rendered against a red background using default lighting (rendered a few times to find the optimal angle), opened the rendering in Photoshop, cut out the red (and took off a pixel of matting to make sure it was gone) then gave it a white stroke. Shadow is simply a skewed version of this. Background is a rounded rectangle using a simple gradient with black stroke.
Don't why so many people bother to include writing in their icons, most of the times you won't be able to read it anyway.
thanks
