animade.tv introduced a challenge called http://fullsecs.com/ where you're given exactly one second to animate whatever you want. The only requirements are to have a 2 second title card and 2 second end slate. Your animation can not involve the title and end slate. They want you to submit the animation to them after uploading it your Vimeo channel. Anyway, you can view their Vimeo channel here https://vimeo.com/channels/fullsecs/102460024

I've started participating in the challenge and of course I'm using TVPaint.

Here are my first three
