-You could do it from a script launched at login
#/bin/bash
while true; do sleep 1200; notify-send -u critical -t 5000 -i
mail-notification "Hogging?" "If someone else is waiting please don't
hog the computer."; done

-Or you could put that command in your crontab (with crontab -e)
*/20 * * * * /usr/bin/notify-send -u critical -t 5000 -i
mail-notification "Hogging?" "If someone else is waiting please don't
hog the computer."

You will need to install libnotify-bin from either synaptic/adept or
"$sudo apt-get install libnotify-bin" To use the fancy notifier stuff.
