My first car-iphoneography experiment a few months ago, shown on http://whatisbelgium.blogspot.be/2012/06/from-antwerp-to-brussels-by-car.html, was fun. I had another try at it.
All of these are taken in Brussels.
1: rue du Bailly.
2: the main cathedral in Brussels (St Michael and St Gudule).
3: street art, Monsieur Jean, the strip character of Dupuy and Berberian
at the corner of rue du Midi
If you're interested in "shooting" while on the go, you might enjoy looking at the photo's on http://500px.com/blog/325/nyc-bike-trips-to-work, by Tim Sklyarov who while traveling to and from work in New York city every day on a bike, documented his daily trips and encounters in 2001.
