I used illustrator to create the paths, then I turned the outlines into shapes... applied gradients and tweaked the sizes. It went through a zillion iterations (actually I don't think this one is the final because the symmetry is off).
I think it took me a couple hours.
no no, not a crit, just stating that it's lame that they didn't use the design. It's freakin sweet lookin and then they just say "Screw it, we're gonna stick with what we have...". That sucks man. It's a nice corporate piece.
