Did you ever spill salt or pepper on the table and sit there pushing it around into different shapes with your finger? Draw in the sand at the beach? Write a message on someone's dirty windshield? Now you can do it on your iPhone or iPod Touch without making a mess!
Dust gives you 10,000 particles to push around and do whatever you want with. Make a snow globe, a zen garden, sand art. It's addicting and somehow soothing. It will keep your kids busy.
Settings allow you to change background color, dust color, dust size, and various physics attributes of the dust for all kinds of experiences. Shake the device to scatter the dust and start again.
