CDG (later known as HARC) was a short-lived research organization, founded by Alan Kay, where I was privileged to work from 2014-2017. As part of Alex Warth’s team, my research was mostly focused on creating new kinds of programming interfaces.
The practical side of our research produced Ohm, a library and language for building parsers, interpreters, compilers, and more. Besides contributing to Ohm itself, I also created the Ohm editor/visualizer to give people a better way to understand and debug their grammars. I’m proud to say that Ohm was a minor success, yielding a couple of conference papers, and even becoming part of the CS curriculum at Loyola Marymount University.
Another more ambitious thread of our research asked: what if programming were more like sketching on a whiteboard? What would it feel like to build dynamic, visual models at the speed of conversation?
Unfortunately, our funding ran out before we could make much progress on that work. But I recently discovered a folder full of gifs and screenshots that I made around that time, and figured I’d post them here for posterity.
