Killer Pool Lite [iTunes link] - Killer Pool gets the lite treatment with a free version of its game. It's a very good pool game. But, it doesn't encourage me to delete Vegas Pool Sharks Lite. Still a worthwhile download if only to try it.
DeloriCam [iTunes link] - While it has a name and logo that is reminiscent of the movie "Back To The Future," it has a very practical use. It takes a picture 5 frames from the past and 5 frames into the future. Then, you select the least blurry picture to save. While that is really cool, it also plays an animation of the 10 frames and gives us a preview of how well an iPhone video camera app could work.
