scgame is a drawing package a la Carbon.
It is based on Xlib for scsh and thus needs scx-0.2.
You can tune config.scm before you start.
Another homebrewed library for the linux framebuffer :
For another working putpixel method check out the scheme48-fb as a basis for
scsh images. You can get it at http://soft.vub.ac.be/~jceuppen/scheme/
fb stands for linux's framebuffer to draw on, the packages are named scheme48-*fb-*.
In the above scheme48-1.8-fb-x11 packages, X11 window drawing is
supported with xputpixel method.
Do read the packages' README and HACKING files if you run into any
problems.
