More and more location data becomes available and makes it possible to visualise the beat of the city over longer periods and/or compressed as a speed up sequence.
Eric Fischer has recently published online a few mappings of online available location data. Most popular were the flickr maps of world cities. This time it is bus movement data through which he visualises San Francisco. The data was collected of the period of one month.

Visualisation of public transport vehicles in Vienna, Austria put together by Max Kossa on wissenbelasted.com . It is built from a database containing 1048 stops along 44 bus lines, 18 night bus lines and 29 tram lines. Within 24 hours there are some 510.026 total stops for all vehicles.
The different vehicle types are coded in colour. Green are the night buses. This is quite obvious at 01:30. At this time the regular service shuts down and the blue (tram) and red (bus) dots vanish for the rest of the night.
The author has published the scraped data base file for download if you want to have a play.
