This is like no other clock app, the Chameleon Clock for iOS powered devices uses the rear camera to take a sample image and this becomes the background on the device, it actually looks like the device is see through! Although we can image that there is some serious setting up to do here.
These are the details for the Chameleon Clock By Netwalk
Toggle the time display between black & white to match your device with a simple tap and change its transparency with a swipe up or down – anything from jet black and pure white all the way down to barely visible for a more subtle effect.
Tap the mode icon in the bottom left hand corner of the screen to switch between Chameleon Mode where the background colour of the screen is constantly updated to match whatever is behind it, and Live Camera Mode where the background becomes a live video feed.
This is app is available now from iTunes and is priced at $0.99 or £0.69.
