You might want to start by looking at Will Ware's NanoCAD molecular
modelling system <URL:ftp://ftp.std.com/pub/wware/nanocad-0.2/unix/README>
which runs on top of MrEd (which is the editor-cum-graphics package
underneath DrScheme). It's fairly simple & readable code, yet contains
some really cool stuff, such as click-and-drag "3-D" rotation of organic
molecules.

[An early version of NCAD was distributed in earlier PLT distributions,
in, for example, "plt.49/mred/demo/ncad02x.ss", but it was later dropped
from the PLT bits...]

You might also look at an unpacked PLT v.101 distribution tree at
"plt/collects/graphics/TREADME" for turtle graphics,
