Set to begin shipment in early August the FLIR One iPhone case features infrared technology. The creators tout the expensive case ($349) as having state-of-the-art thermal imaging technology developed by the military. This technology was only available to the military just a few years ago.
They say you can now see and photograph the world in a totally new way. Sounds kind of novel for the lay person but the creators are also saying it has numerous practical applications. Is there danger lurking in the woods while camping or hunting? Are you jogging on a foggy night and need to spot possible threats? How about electrical and plumbing issues in the house?
I found this video from MacWorld 2014 that showcases some of it's features. You can also check out FLIR One's website here
