Aclock is an ASCII (text-mode) Analog Clock for consoles, terminals, or terminal emulators. This program is obviously absolutely useless, except for turning your old, expensive mainframe or supercomputer into a nice clock.
The font used should be near 1/2 ratio - for example 6x12 or 7x14. On text based terminals you usually have something around 8/16 which is perfect.
UNIX source code compiles on everything from AIX to zOS without any changes. Also included are experimental AAlib enhanced version and CGIC/GDLIB version for web.
