I've nicked this from Cally Taylor's blog (sorry, but is for a good cause).
Caroline Smailes is holding a writing challenge for charity.
All you have to do is submit a piece of flash fiction (no more than 100 words) based on a youtube clip.
The stories selected will be made into an ebook, with the money made going to charity.
All the details are here.
Warning - the closing date is Wednesday 11th January so get cracking!
