I at one time (with a similar goal as you) was working on a simple Perl
library that'd write Tektronic graphic sequences to a file (via a
LOGOist interface, a` la pen_up, pen_down, etc), which I'd then play
back with MSKermit via some MSDOS command line hokum.
The same thing could be done with whatever terminals MSKermit can
emulate.
Or if one were using an MSDOS machine under DOS with ANSI.SYS loaded,
one can just print ANSI sequences to STDOUT.  (Not that ANSI == VT100,
mind you).  I've fiddled with that a bit, too.

I vaguely recall thinking about whether this plan of operation (using a
Kermit to play back files of terminal sequences) wousd be feasable on a
Mac, and to that end I DL'd a copy of Mac Kermit -- but I found it so
unstable a binary that I don't think I ever even got it to do anything
without hanging my machine.
