Here's a 4 minute video of a Jeep getting torn down and reassembled: http://www.wimp.com/rebuildjeep/ Sent in by Team WIKISPEED member Bob Stuart. He titled the post "Historic Modularity".
This is awesome, and good to see the evidence of how modularity has evolved. The module contracts in software are broad, so as many types of devices/software can connect to them as responsible. Think USB- it isn't just keyboards, but printers, Christmas trees, Nerf missile batteries. If the jeep suspension allowed tank treads or many types of articulated legs to be attached without changing the rest of the jeep- then it would be modular. As it sits- what Willys did in 1941 was amazing- they maximized the speed and efficiency to swap interchangeable parts, and then software maximized the speed to make change (Agile). What might come next?
