Have you ever wondered where things come from ? Sourcemap is a free, open-source project aiming to show you where every day items are made and where their components originate.
It does this by linking manufacturers with supply chains in a Google Maps mash-up, rendering lines between those locations. The site also provides an option to view the maps in 3D, in Google Earth. Simply browse the website to view maps made by others, or register to create your own.
This embedded map, based on data from an article in PC Magazine, shows the provenance of a typical laptop computer made in Shanghai, China.
