I recently entered a competition on the E4 TV channel in the UK. They have 10 second "E Stings" between programmes to advertise the channel. Each year there's a competition to create new ones. Here's a still from mine.
I created 3D models of the chicken and the fish from the E Stings that are currently being broadcast (yes, I asked for and received permission :-) )
Quick edit. I forgot to include the URL to the 10 second animation: https://www.youtube.com/watch?v=kKOxhhcbn6Q
Thanks :-), no sadly not. There was a serious issue with Twitter. The contest only allowed entries by tweeting and I very rarely do that. It appears that Twitter doesn't index all tweets, so I don't think they even saw it. They wouldn't even check to confirm the entry after I contacted their customer support.
Fun video. Did it get aired?
