Changing the suntools background by program

[Peter Li]

As a result of playing with System V IPC, I found a way to change the
suntools background by using another process. The fastest update frequency
is around one per second on a Sun 3/50. It requires a kernel with IPCSHMEM
and IPCSEMAPHORE options compiled. The patch to suntools.c is based on
Version 1.7 87/05/04. The background changing program is based on
stringart. It is readily modifiable to suit your own needs.
