We first mentioned the Windows Phone app Torchbear a couple of months ago when the developer needed beta testers. Well, the kinks have been ironed out and Torchbear has left the Beta stages and is now available over at the Windows Phone Marketplace.
What is Torchbear you ask? Torchbear is described as a mobile geolocation based social network game. You create a torch that can be a thought, idea or image. You then create a mission for your torch and share it with other Torchbear users around the world.
For example, you can create a torch calling for the posting of photos that make you think of the fall season (that's the mission) and add your own photo to the torch. You then monitor how many exchanges, comments, and followers keep the torch burning. You can also monitor how far the torch has traveled. You can even map out where your torch has been and monitor your torches progress from Torchbear's website. The goal is to generate the most activity from your torch.
You do have to register with Torchbear (free) and it's interesting to see how far your torches can travel around the globe. Torchbear is a free app and you can find it here at the Windows Phone Marketplace.
