A simple diversion for the iPhone and iPod touch. FireworksToy is a very simple little application that displays fireworks on your iPhone or iPhone touch. Start the application and enjoy your very own soothing fireworks display. The fireworks respond to gravity. No matter how you orient your device, the fireworks will always fall "down". Tap on the screen and a firework will be launched towards the location you tapped. Drag your fingers across the screen and dozens of colorful fireworks will be launched towards the path your fingers traced. TIP: use your device's built-in Safari browser along with your favorite search engine to find images of your favorite cities or landmarks at night. Next, you can tap and hold on the pictures to save them to your camera roll. Now they'll be available to use as backgrounds in FireworksToy! PLEASE NOTE: FireworksToy was originally created as the victory overlay for Mü but Steve thought that it was fun enough to play with that he decided to also release it for FREE as a stand-alone application. We realize that this is hardly a top-tier application but we thought that making it available for FREE would be a NICE gesture. Those of you who are expecting more should probably look elsewhere. To the rest of you: we hope you enjoy playing with it!
