The Lytro Illum is the kind of product that I don't know how to describe. It's a camera, but the technology inside is so...kind of mindblowing that it has potential for much wider appeal. First though, you'll need to throw away everything you know about the principles of photography—the rule of thirds, shooting for depth, the golden ratio—all of it. Lytro touts what the Illum shoots as "living photographs", capturing images that can change depth of field in real-time. It might sound gimmicky, but in reality, it's incredible to behold. You're able to zoom, pan, and rack focus all at once and the results can be staggering.
You need to see it in action to really appreciate it; find a gallery here.
If you're impressed (and have $1,500 burning a hole in your pocket), Lytro's Illum can be yours today. According to The Verge, it still has a ways to go, but swinging the fences has it's merits.
