The ability to "psh" to the NeWS server and play around with PostScript (much like the Chrome Developer Tools now lets you do with JavaScript) was crucial to making NeWS fun. The PSIBER Space Deck was trying to make a visual Smalltalk-like or Lisp-Machine-like development and debugging environment for NeWS, that let you visually browse and edit PostScript code and data structures and objects and processes in the system. https://medium.com/@donhopkins/the-shape-of-psiber-space-oct... The Shape of PSIBER Space: PostScript Interactive Bug Eradication Routines — October 1989 Written by Don Hopkins, October 1989.
University of Maryland Human-Computer Interaction Lab, Computer Science Department, College Park, Maryland 20742. Abstract The PSIBER Space Deck is an interactive visual user interface to a graphical programming environment, the NeWS window system. It lets you display, manipulate, and navigate the data structures, programs, and processes living in the virtual memory space of NeWS. It is useful as a debugging tool, and as a hands on way to learn about programming in PostScript and NeWS. |

And here are some ideas about visual programming and programming by demonstrations that I was thinking about while developing PSIBER, like a visually programmable window shell environment:
