Here's the current homepage of Channel4's new(ish) PC VOD service. Ugly Betty (eps 1 and 2) and Desperate Housewives are free at the moment - although you do need XP and you have to download and install an app.
From a two week animation course three years ago. The first week we messed around, and in the second week we each made a short piece. This piece is 18 seconds long although the actual animated parts are probably less than 8 seconds.
