This is a reworked version of Brian Mastenbrook's sb-screen updated to use cffi and trivial gray streams. It should be a workable alternative to cl-ncurses. Two streams are provided - one for output to the whole screen, one for output to a defined window. The licence remains BSD.
It is really intended for roguelike games or interactive fiction and other similarly graphically undemanding passtimes.
The latest version available for download is cl-screen-0.9
