A novel new free app called iSteam (App Store link) is now available in the App Store. iSteam will create the effect of steam on your iPhone, without the steam room. iSteam works with photos in your library. You blow into the microphone to create the steam. From there you can draw as if it were real steam. Although there is not save option, you can simply use the iPhone's built-in screenshot to save your masterpieces. To do so, just press the power button and the home button at the same time. Be careful not to move your iPhone, as iSteam has accelerometer support and you will see water droplets flowing across your screen.
