Nikolai Khabibulin of Team Russia of Ice Hockey has a pink floyd design on his goalie helmet. Basically, the helmet is painted to look like The Wall, with "The Wall" written on the bottom. On one side a few of the bricks are missing, and instead of marching hammers being behind the wall, there are marching hockey sticks.

This site has pictures and lots of info about it, so check it out, http://www.khabibulin.com/gear.html
