Incase has introduced a new version of its popular Snap Case made with a heat-activated thermochromatic finish. The $35 pink Thermo Snap Case changes color when held, like heat-activated t-shirts from the 80's.

Incase may be the most recent case-maker to release a color-changing case, but they are far from the only one. XtremeMac offers the $30 Tuffwrap Shift that has a similar design to the Snap Case, but is available in a wider variety of color schemes: blue/white; pink/white; purple/blue; grey/white; green/white; and orange/yellow.

Finally, RF Laserworks offers a $12 heat sensitive iPhone 4 backing that's .005" thick, meaning it's designed to fit under a bumper or other case.
Thermochromatic cases don't quite work like the XtremeMac press photograph above, showing off fine details and fingerprints. However, they can bring something a little different to the iPhone case world.
All the cases mentioned are compatible with both the iPhone 4 and the 4S.

I know the case is da bomb, but really...:D
Now that's a throwback. I was one of those kids who just wasn't cool, and I remember begging my parents to let me have a Hypercolor T-shirt. I wore it so proudly to school. And I loved when girls came up and breathed on it to try it out.
The 1970s called as well, and want their mood rings back.
:p
