We had some Apollo Domain machines at school which could also run similar programs - I remember 'Crumble' and 'Melt' being two of them. And you could run them on other peoples' display. So we used to melt/crumble the screens of the engineering students in the next lab over. 'We' in this case had admin privileges, though, and only did it a couple of times.
