I'm glad to announce Picture to People site has a new class of effects I have not made disclosure in this blog yet.
P2P has the "pattern effects". For Picture to People, a "pattern" is a black shape in a white background. This new approach gives a whole world of new possibilities, since you can use ANY black and white image you want.
Soon I will start a Tutorial section in www.picturetopeople.org, so, among other things, I will show tips, tricks and pitfalls of pre-processing your patterns to get the best results concerning the effects.
