what I mean by “scraper (?)” is that I don’t know what it’s called in english…
It’s like a lotteryticket, and you scrape of a layer, and under the layer it’s different numbers or something like that…
Hope you understand!
Anyways, I saw a great tute on that like a month ago, but I didn’t care about it then, but now I want to know 
The basic is making a drawingboard that is a mask I guess, but I’m not good at the drawing API (yet), so I can’t do it on my own.
So, if you have seen the tute (or a similar), can you please post a link to it here?
thanks in advance (I hope)
