Introducing, the Miharu Intraoral Camera.
From their website:
Using the Miharu intraoral dental camera, tartar and dental plaque become visible (illuminated) by the one touch mode changer. It’s also useful on many other parts of the body such as the back, skin, head, etc for easy and sanitary viewing.I predict that this item is going to be used in many unexpected (or expected but unintended) ways.
We'll be seeing DIY Endoscopy Art on Boing Boing soon enough. YouTube will be awash in videos of places you just don't want to go. Then the hacks will come along. Someone will hook it up to their Wii or work it into some sort of surveillance or voyeurism mod.
