Wolfire offers downloads of its Humble Indie Bundle #3 for Windows or Mac for whatever you want to pay. If you opt to pay the bare minimum of 1 cent, that's a $50 savings and the best deal we've seen for this 5-game, DRM-free bundle. It includes VVVVVV, Cogs, Hammerfight, Crayon Physics Deluxe, and And Yet It Moves. Your contribution can be donated to charity (EFF and Child's Play), the developers, or both.
