Skins Opening Credits

I have been a big fan of these opening credits for Channel 4's "Skins" program for some time. They begin with a psychedelic montage (quite kaleidoscopic) before chopping into various small snippets from the entire series. These snippets are constantly changing, heavily treated with various effects, mattes made from spliff-smoke, all blended together and also synced perfectly to the theme tune. The sum of these parts is its strength.

The whole piece is only 28 seconds long, and I am particularly keen on the masking they use, which eventually reveals the type logo 'skins' towards the end, and am keen to learn many of these techniques asap. I am loosely referring to this for my Observer Brief.

I am also keen to know who did them. I have looked, but haven't sussed it yet.
