SuSE Linux 10.1 , set up so that it will boot the way you expect; also will 'autorun' under Microsoft Windows; and will run as a Microsoft Windows screensaver. Uses QEMU to run under Windows; rather slow, but functionally fine. Linux gets everywhere ! I wonder, will anyone want to put it on their preload ? No reason they shouldn't, provided they put source code on too, to keep the GPL sweet. Great marketing novelty, I reckon. Jamming along nicely ... Oh, I forgot. To end the screensaver, the fastest way is to do Ctrl-Alt-F, then click on the red 'X'.

I have used the screen shot from that one; I'll update it when I can
