Who says mp3 player cases can't be dynamic? Improv Electronics launches the Skin Flik, the colour-changing device case for iPod Touch 2/3G.

The case carries a Reflex electronic skin with integrated LCDs, alongside a touch sensitive strip. Swiping a finger over the strip lights up the LCDs, causing the colour change.

The LCDs lie beneath a clear plastic lens printed with a graphic image, parts of which remain clear to reveal the skin beneath.

It also doesn't use power from the device, as it uses two 3V coin cell batteries (included).
