EnvDraw
EnvDraw is a program I wrote in the summer of 1995 to aid students in
the introductory CS class here at UCB understand environment diagrams
and box and pointer structures in scheme. The latest version of
EnvDraw uses STk version 3.1.x, though versions are available running

It produces diagrams like the following:
