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
OMG Hypercolor.
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 1990s called, said they wanted their futuristic disco cases back.
The 1970s called as well, and want their mood rings back.
:p
