the directories are such:

life   - life simulation
vega   - 2D figure rotation, vector graphics, figure specified by mouse
vega3  - 3D figure rotation
vega31 - 3D figure rotation, also allows for 4 different figures and hides
         invisible sides

these were developed on a dn3k with a 1280x1024 mono monitor, so that's
what it's compiled for by default. it was also tried on a dn3k with
1024x800 color (4-plane) monitor, so that's compiled using:
cc -DCOLOR -DSMALL file.c -o file
(some of the above programs don't recognize the SMALL switch, they
automatically assume COLOR means SMALL, i think the vega31 recognizes
both).
the binaries are SR9.7 obj-type. i think they work on SR10.x systems (i
checked it once, it worked, but i don't know to what extent). they might
even compile on SR10.x, but i didn't check that yet.
each directory should have it's own README file that has specific info
about the program.
all the programs expect to be broken by ^Q - they don't have any EXIT key.
thanks.
