One of the coolest things to come out of the 2014 Consumer Electronics Show is the FLIR One iPhone case! FLIR is a brand name for thermal imaging cameras. This case will fit an iPhone 5 or 5s, has a FLIR camera built in as well as a battery pack that extends your battery life by about 50% (or 2 hours of continuous use). The FLIR One iPhone case is expected to be available later this year and should retail for around $350.
Uses: Checking for drafts or poorly insulated areas of your house, locating your friends in a dark campground or hunting for bigfoot.
