Get a bike. Lock it to a post. Take a pic every day for a year.
Last year, we conducted a unique urban experiment for Hudson Urban Bicycles. On January 1, 2011 we chained a fully loaded bike - bells, basket, lights and more - to a post along a busy Soho street. We took a picture of the bike everyday for 365 days, watching it slowly vanish before our eyes. The photos we took were then turned into a daily calendar. We call this project LIFECYCLE: 365 days in the life of a bike in NYC.
