I've now written a second iphone application, this time to publicize the US version of the Undercover Scientist book, which is called Why Sh*t Happens. The program is called "iSmash" - it allows you to choose your own images and then "smash" them, with appropriate sound effects.

For those interested in how it was created here's a few gory details: The image of the glass is made from four photos of a real piece of glass that I smashed (carefully) with a hammer. Depending on the angle of the device, different images are merged together to give the impression that the light is changing. Underneath the photos are four partially translucent patterns of shaded glass which are also merged together differently depending on the angle. Underneath that, your five images are randomly shown.

Note that this is a simulation of a smashed image - there is absolutely nothing wrong with your device and pressing the "Home" button will quit the application as normal. If you have any problems with the program then leave a message on this page and I'll try and leave a reply here in a few days. I'll do a YouTube video for the app soon. iSmash is now available on Cydia, hosted by bigboss so anyone with a jalibroken iPod Touch or iPhone can enjoy the app.

If you like the application, please do check out the book by touching the screen during the countdown - you should enjoy it too!

Enjoy iSmash!
