Algorithm for Generating Symmetric Pictures

Hi I just joined and have a simple question. You know the patterns that we get when we join? Does anyone have an algorithm or program to generate them? I am also interested in progrms or algorithms that can generate "Mandalas" (Tibetan or Buddhist). I am nor sure what makes a picture a mandala, except that usually they are approximately circular and have various levels of symmetry. Any leads or answers w开发者_如何学运维ould be appreciated!

Those patterns are called identicons. You can read more about them and how they're generated here. You can see and download a sample PHP implementation of the concept here.

Do a google search on the "17 Wallpaper Patterns".

It's a fascinating area if you are interested in this. When I last looked (10 years ago) there were several applications that generated them. I wrote one in my final semester of university.
