zone

In emacs, try

(require 'zone)
(setq zone-idle 120)

(setq zone-programs '(zone-pgm-whack-chars
                      zone-pgm-five-oclock-swan-dive
                      zone-pgm-martini-swan-dive
                      zone-pgm-drip
                      zone-pgm-drip-fretfully
                      ))

(zone-when-idle zone-idle)

These are hilarious. Especially the drip-fretfully.
