Descriptions:

A fluorescent firework is filling your screen. A bundle of light follows your finger. Ever changing rainbow colors come down like a never ending meteor-shower. When you double tap on the screen the little shooting stars combust into thousands of particles. The composition of colors are beautiful and you won?t get bored watching the spectacle for hours. The truly amazing thing about this application is how well the automatic generation of particles blends together with the explicit control of your finger. It feels like your action is an extension of the intelligence that the light objects posses already. It?s a true unique application that has come to the iPhone that you will not regret buying. Oh and if you want to save your art you can simply use the screen capture function (hold home & lock) of the iPhone. Those patterns make for great artistic images for Christmas cards. Let the show begin!

Alternative:

What an amazing application, it?s like a firework on steroids! The best part is that you have full control over every aspect of it without having to open any options dialog. You can control the path of the light objects with your finger, change the color through pinching at the right location, change the tail length, size, speed, everything and to top it all off you double tap the screen and all particles instantly combust into a thousand offspring. The little particles will never get tired of amazing you with ever changing new beautiful artistic constellations and neither will you get tired of watching them doing their thing. Highly recommended!

Original Description in iTunes:

Spawn is a program that creates amazing animations of little particles that are influenced by different forces. Without user interaction the forces are chosen randomly and the particle seems to have a mind of their own, flying around, reacting to gravity and invisible force fields.

The mesmerizing patterns created are reminiscent of fireworks, sea anemones, electrons in a cloud chamber, or tiny organisms under a microscope.

You can exert control over the particles by touching the screen and dragging your finger. The ever color changing particles will follow and circle your finger wherever you move it. Double tap the screen to see them explode, spawning a mass of new particles in all directions. Spread or pinch horizontally (center) and the particles will fly faster or slower. Spread or pinch vertically (center) and the particles will become bigger or smaller. Spread or pinch vertically (left side) and the particles will have a longer or shorter trail. Spread or pinch vertically (right side) and the particles will change color.

By changing the combinations one can create endless patterns that can be saved as images to your phone by pressing the home button and the lock button at the same time. Check out our product page at www.eodsoft.com/Spawn for a set of sample images (and video) created by Spawn. While Spawn is as much fun as a game it is more like an interactive screensaver simulation.

So it?s late and your local liquor store is closed. Well, instead of just dealing with it or heading to a bar, you could always load up iBeer for the iPhone and iPod Touch. This app lets you pour a virtual glass of beer onto your iPhone screen and then drink it.
This app starts off with one big giant button that you get to press. Once you press it, the screen goes black and then fills with a nice presumably cold beer. The details of the beer are pretty decent. You can see the carbonation and the head seems to diminish over time. Once you?ve stared at it long enough, your next step is to put that iPhone up to your lips and pretend your drinking. Delicious.
If you?d like to mess around with a few different options, press and hold your finger on the beer when it?s fully filled. This will bring up the setting screen that has a series of on and off switches so you can make that beer your own. Besides that, it?s back to drinking your fake beer or time to quit the app.
It?s confusing as to how this app became so popular. It started out as a video that you could purchase for your iPhone and then flourished into its own app. There isn?t anything wonderful or interesting about this app. In fact, after the first use, you?ll probably not want to play with it again. If you some how manage to use it five times, you?ve probably got your monies worth.
