Mining for bitcoins on GPUs is fun, especially if you have 3 video cards in one system. This income can, however, be supplemented by some foraging for free micro-bitcoins. This does not bring much to your wallet, but the total amount can be acceptable if the foraging does not require much of your time.
Below is a selection of sites, which I found to be more productive and less demanding on your attention. This list is compiled from a much wider selection, presented in this thread on Bitcointalk.
