There was supposed to be a free .mat file to go with the tut, which I cant see (yet), so if you want to try it out, I attached the zipped file here. Download, rename it so it doesnt have the '.txt' extension and unzip it.

...and something completely OT:
may I appologize to all those I've upset last year. It is is the Jewish 'Yom Kippur' (atonement day) tomorrow. I'm nor religious, but it's a good tradition to ask for forgivness from anyone I hurt, at least once a year.

Maybe next year I'll be less annoying?

"I paint that which comes from the imagination or from dreams, or from an unconscious drive. I photograph the things that I do not wish to paint, the things which already have an existence."
Man Ray, modernist painter
