Francis released an update ot his application Waves.
Waves is a small toy for your apple iPhone or iPod touch. You can select a predefined image or your own wallpaper and you can touch the screen to generate some wave effect over the image. A floating button can also be added in order to generate the effect in the different screens of the device (i.e. the picture app).
Release notes:
Hi, There is a sporadic problem with the 1.1 version of Waves causing sometimes some troubles during the device reboot when the floating button is enabled.
That's why a 1.1-1 version has been put on the installer in order to remove it from your device before I can make a fix.
The download is currently removed from this page too.
Sorry for the troubles.
Francis.
