Whoa what on earth is this Scheme evaluation visualization tool named EnvDraw made in Hoot? https://jmacd.github.io/envdraw/

And apparently EnvDraw has existed since 1995 and this is a port! Here's an old mailing list post https://groups.google.com/g/comp.lang.scheme/c/AU3HKB9plKk/m/TCkArQA51rcJ

Cool as hell
