Yes, I found this earlier today, too. Impressive scripting. But on the Amiga one he's mixed 1.3 and 3.x together! (and I don't think Workbench actually has a restart prompt)
I enjoyed the Rhapsody one, which prompted me to learn a bit more about this system. I knew it was related to OSX, but I had no idea how closely until today. OSX *is* Rhapsody/NeXT. Wow!
That's what i thought too but then i am only using 1.3 and not 3.x

Also there are a couple of them i do not recognise. Anyone care to fill me in?
