Hemisphere Games and Macgamestore.com have announced a Mac version of the indie game Osmos. The software features physics-based gameplay and allows players to take control of a mote that must grow by absorbing other motes. Players propel themselves and move around space by ejecting matter behind them, however, by doing so, the mote loses mass and becomes more vulnerable. Players will interact with attractors, repulsors, and other intelligent motes with similar abilities and goals.
