SandScapes is a particle generator for the iPhone. Included are 8 different types, some interactive and some to sit back and enjoy. The interactive modules allow you to tilt and turn your iPhone or iPod Touch to move the falling sand to different parts of the screen. Simple yet very engaging, some of the the modules,Â especiallyÂ the interactive ones where you are able to add emitters, are a real pleasure to play with. In addition if you find that you want to save images there is a "capture screen" button available and a number of settings specific to each module.
