'Pokies Style' Social Icons

Ok, so I made a sprite with all of my social icons required for my website - but then realised that I wanted them to all be 'washed out' but then fade to color on rollover. However, since I was using just one sprite for all of them, this was not possible - but by mistake I managed to get them to animate like a vertical spinning wheel (like on a pokie machine) - until it 'locked' into the correct colour version.

Anyway, I think this effect is kinda cool and adds a little bit of spice to the page.

To view it, just go to http://william.rainbird.me/ and scroll down to the bottom :)

The icon set is by Gedy - thanks :)
