Some of this is more useful over ssh than using the machine locally.
I can:
play music / alarms (hint: make the computer play a alarm while someone else is using it if you want them off of it)
set the fan speed on a G4
kill programs
open GUI and command line programs
logout all GUI users (sudo kill (loginwindow's pid))
SSH (of course)
search (mdfind)
Make the computer talk (I forgot that one. It is fun to make the computer talk over ssh while someone else is using the computer)
Control iTunes (really scares people who do not know you can do this)
write shell scripts
