That is, provided those ghosts are interested in messing around with your iPhone. Here’s hoping they don’t figure out your password. The Thermo Snap case is a hard case for the iPhone 4S with a nod to fashion trends of yesterday. The case is outfitted with thermochromic material that lightens color in response to heat transferred through touch or breath. Useful if you want to detect the presence of tech-loving spirits, or if you just want to see your handprint on your phone every time you use it.
The Thermo Snap Case is available in pink on the incase website for about $35.
