The monospaced bitmap font from IBM's 1985 'ASCII Display Station' (terminal), the IBM 3161. Includes versions for a multitude of devices and platforms. (Also on gitlab: https://gitlab.com/wyatt8740/IBM3161-font)
(Also on GitLab - https://gitlab.com/wyatt8740/x11-window-hider.git ) - Easily hide and show (unmap and map) X11 windows. libxcb ANSI (C89) compatible C and bash xdotool implementations.
A Python/TK/Korn Shell-based GUI wrapper for `xwd`, the X11 Window Dumper tool. Now primarily focused on using `ffmpeg` instead, but both ways work. Designed to work as a screenshot tool for CDE, but should work anywhere.
