ManyCam – 1 webcam for all IMs with many additional cool effects
One day, I wanted to use my webcam for two instant messaging programs even though I knew that wasn't possible. Frustrated, I stumbled upon ManyCam a few days later, and we were a match made in heaven. ManyCam is the answer to the problem most people who want to use their webcam in several applications have. It acts as a virtual camera for multiple applications at the same time offering many additional features on top of it. You can change your background, appear as if it's snowing in your room, put on funny masks, draw on your webcam and many more.
