Cell phone tech has grown by leaps and bounds. You can do damn near everything with your pocket rocket these days. Including perform your own colonoscopy! If you're into that.

Cellrizon is the company that makes this new tiny camera that attaches directly to your phone. They aren't technically marketing it for home colonoscopies per se, but you could use if for one if you wanted to. The camera is supposed to just be convenient to reach into small spaces and show you things you can't already see, like in your car's engine, or your kitchen sink pipes or something. But I don't see why it wouldn't work for medical purposes too. Watch the video. I guarantee somebody will put this in their butt. Its waterproof already, so why not!

Unfortunately for me its only for Android phones right now. Otherwise this would be a totally different video I posted here.
