The trick was to infiltrate as many surreptitious background tasks to slow your opponents machine down before they noticed and started running tasks on your display. Santa claus, cockroaches, ants, stars, shiny 3d edges to background windows etc.
The trouble was it escalated pretty much like real wars do in terms of weaponry and eventually everyone had scripts that could detect the tasks being run and ran a barrage of counter-tasks against the source address.
The war was finally ended when someone *cough* spoofed the manager's IP address which triggered the target's nuclear-task script to completely obliterate the managers desktop environment.
Up until that point the manager didn't know this war was even going on - it was very funny to see his reaction to all those 'eyes' and clocks and cockroaches suddenly appearing on his screen. Happy days. If you tried that now you wouldn't only be sacked you'd be imprisoned without trial as a terrorist.
And yes, this final tactic was inspired by Terminator :)
