I've had this idea for ages, since I saw footage of dust devils on Mars like this on The Sky At Night a few years ago.
I don't know if it's any good or if it makes sense to anybody else, or whether it needs lots of development etc, but I kinda like how it is in my head. It's simple, but probably a bit obscure for anyone to get what it's about - I mean, does anyone actually watch The Sky At Night? Or does it matter?
Anyway, here's the script I wrote ages ago. I'm working on a re-write to get a bit more of a story in there, but let me know what you think...I'm thinking about taking this on for the second part of the Narrative module, using similar techniques to The Lyre Of Orpheus thing I did, but with more traditionally animated bits.
