Adam sent word of this interesting piece – A physical manifestation add-on for a first-person-shooter game, Riley C Harmon’s “What it is without the hand that wields it” –
Custom electronics based on an Atmega8/168 micro-controller are connected to a PC running a dedicated Counter-strike Source server. Players across the internet can connect and play live on the server, and each time a player dies, a java script written in Processing sends serial commands to the micro-controller, telling it to spray fake blood.
A sort of sensory/mental tax for simulated violence?
