Hit + Run Crew is the name of an L.A.-based print shop with a novel way of doing business: They do their manufacturing in public.

Founders Brandy Flower and Mike Crivello have designed and built a portable T-shirt silkscreening rig that breaks down into a flight case. They then bring five of these on-site to events--parties, concerts, conferences, street fairs, etc.--and set up a mobile factory, where participants can select patterns and have shirts printed on-demand.

Hit + Run's set-up time is less than an hour, and over the course of a three- to six-hour event they can crank out 100-500 shirts. Here's their self-produced video showing what they do:

They were also featured in this mini-doc, released just two days ago, on L.A.-area print shops:

Their success speaks to an obvious fact: People love seeing stuff being made. 3D printers might not yet be fast enough to match the rate at which Hit + Run can produce, but we expect that as the technology advances, we'll see entrepreneurs adapting Hit + Run's model for industrial design.
