For those GUI fanatics among us (including myself), here is a site that covers the development of the Apple Lisa GUI and desktop: http://home.san.rr.com/deans/lisagui.html Nearly every GUI and desktop in use today can trace its ancestry back to the Lisa, for better or worse. (BTW, I believe Loci's workspace is not a direct descendant of Lisa's desktop. We're rethinking quite a few things.) The screenshots page of prototypes is very interesting. Note that the first prototype was made on an Apple II in 1979 (!) http://home.san.rr.com/deans/prototypes.html Cheers. Jeff
