Ah yes, I remember the funny guy facing various dramatic software difficulties in the first part of the video. This builder does look like a precursor to NeXT's and HyperCard too. I like that the "toolbox" appears next to the mouse, instead of having to go to the top menu or sidebar to select a new tool and back to position to use it. I missed that it ran on a Lisp processor, very cool! And that the main developer later worked at NeXT and Apple. > Jean-Marie Hullot authored important programs for the original Macintosh, NeXTSTEP and Mac OS X platforms. These include SOS Interface for the Mac, which later became Interface Builder for NeXTSTEP (1985), and later still evolved into an important part of Mac OS X. > He also came up with the idea of the iPhone and led the iCal and iSync development teams for Mac OS X (2002). https://en.wikipedia.org/wiki/Jean-Marie_Hullot https://en.wikipedia.org/wiki/Jean-Marie_Hullot ..Searching for "SOS Interface for the Mac", I guess it's Sophisticated Operating System, "the primary operating system of the Apple III computer" released in 1980. https://en.wikipedia.org/wiki/Apple_SOS https://en.wikipedia.org/wiki/Apple_SOS
