This is apparently a working camera created by artist Wayne Martin Belger. It's called 'Untouchable HIV Camera'.
Jockohomo writes: "The unit which looks like a cross between a prehistoric pacemaker, diesel engine and camera was designed to study and photograph a geographic comparison of people suffering from HIV. Made from Aluminium, Copper, Titanium, Acrylic and HIV positive blood. The blood pumps through the working camera to settle into a pinhole thus creating a #25 red filter."
