I play with the original apophysis a lot because it seems I can get better results sometimes. Last night I came across something I have never seen. I took a screen shot in case any of you have encounteret it. The white box is around a little green circle. Three triangles and that weird little circle. I didn't have time to fool with it to see what it does, but I did save the file. So, if I fool with it, will my computer blow up? *grins* Miriah
