Some of you may have heard of an app I've been working on called lociicycle, as the title suggests it's and app for playing Bike Tag. I've been testing it in Cambridge and I also held an Alley Cat with the Bike Ambulance back in February.
You can browse all the photos of bikes (called Tags) that have been taken around Cambridge. When you go find place it was taken you respond with a new photo there. You can take a photo of your bike wherever you like, but you can only upload it for others to find when you have found someone else's Tag.
The idea is that this will give the game of Bike Tag a bit of momentum. It's be a great way to make a commute more interesting of give= a reason to go and explore for the fun of it.
