Pong is an all-time classic, one of these games that will stick around for generations. Bubblegym takes a different twist on the game by utilizing Mac's Sudden Motion Sensor (SMS) technology. Although this gives a highly original turn to the game, it also makes it much more difficult...and not to say perilous for your Mac laptop. The graphics are still a bit raw and feel more like a game running on Mac OS 9 more than anything but the classical music playing in the background sounds nice. Naturally the game is only limited to those who have a Mac laptop. Great use of Mac's SMS technology, but there's only so long you can play the game, as moving your laptop around gets tiring after a while.
