(Nothing special, just a hobby - famous last words.) I have a web page of it running with some explanations of what you see here: http://cgfreak.sourceforge.net/ The basic idea is that resources can often be represented in piecharts, everyone should be familiar with these from school and economists love them. So I visualize system resources in control groups as piecharts and now I have also started to make it a bit interactive. It all grew out of the educational need to understand scheduling and control groups. I don't know if you think this is as fun as I think, it's nice images anyway, I don't know how accurate they are, feedback and patches welcome. Linus Walleij
