I was a fan of HyperNeWS, but although PostScript could be fun, I found it hard work, and used literate programming for the experimental data analysis system I worked on. It was notable that you could easily try different designs for GUI elements, like sliders I remember. It was impressive that HyperNeWS depended on a meta-circular evaluator for some reason I forget, and was still fast enough on the Sun hardware of the time (SPARCstation 1+, I think). One thing missing was any kind of security for the networking as far as I remember, but it allowed you to build more general distributed systems than just client and graphics server. "Scott McNealy ate my window system" I think was the refrain when it was killed off.
