(Via), this Neverending Drawing project (by Oskar Karlin) is very neat:
Never ending drawing is a project I started in Stockholm five years ago. Inspired by Douglas Coupland’s book Microserfs, Paul Auster’s New York Trilogy and some drawings made by my sister I started mapping my movements in the city. I downloaded a map over Stockholm and pasted it into Illustrator and drew my movents in separate layers each day. After two years I moved to Berlin and then London and continued the project there. Earlier this year during a trip I also mapped my movements in Los Angeles, San Francisco and New York.My limitations are a defined area around the central parts of the city I am in. So if I go outside the “borders” I don’t map it out. You could call it vacation. Since all the data is stored in vector format it is easy to work with.
An example: on the left is is Stockholm, Berlin and London on top of each other, and on the right, it's basically the same as but instead of outlinesKarlin have filled each day with a color with low transparency(Stockholm is green, Berlin is red and London is blue).
Why do I blog this? I like this sort of visualization/city mapping; the chaos created is intriguing and quite situationist. Overlaps are pertinent, maybe this is an instantiation of the Global City.
