Thank you Paula! I find that one of the best ways to understand something is by trying to explain it to others. If I cant explain it - I probably dint understand it properly:)
 I dont want to push the good people at geekatplay to hurry up and post the tutorial, I'm sure they have things to do. But I thought it will be nice if it's available if people want to look at it in the weekend so I uploaded it  to 'yousendit.com'  meanwhile.
The link is

It will only be there for a week, but hopefully by then it will be on G@P.
The zip file contains the tutorial in a pdf file as well as an html file with the associated jpg files for the illustrations. I think the quality of the illustrations is better in the html version, however Icreated it using OpenOffice on a mac so I cant garrantee it works on PCs.
There is also a material (.mat) file you can use if you want to try out the method.
Let me know if you have problems/questions/suggestion. This is my first tutorial, I'm still learning:)

"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
