This is quite a simple app. It lets you continuously take photos with your camera. You run this app instead of your camera app, press the shutter button and of it goes, trying to fill up your memory card as fast as it can! When you have had enough you press the shutter button again and it will display your slideshow of photos. This is handy if you want to quickly take a lot of photos, at a sporting event or something similar. Below is a quick shot out of the window. As you can see the slides all appear along the bottom of the screen and if you press the arrows it advances through the photos.
