Not sure exactly what's on there, but I'd guess part of it at least is the cool screensaver demos they use on the Macs running in Apple Stores. If you or anyone here end up with one, please post the disk image somewhere!
Finally I came to uploading it to MacintoshGarden, had some stressful weeks... See here please
Yes, it is a .cdr and has no hash sum checking, but that will follow - as soon as I have my AlBook around me again. TiBook and the two iBooks refuse to create a .dmg with check sum and end up with a weird error
