OK, so I tool around with my blu-ray quite a lot (Thanks LPF!!) and stumbled upon this. It is a must try if you haven't already:
At night when all is dark turn the lights off, stand in front of a mirror, don appropriate eye protection, smile big and start blasting your teeth one by one. A lot of "hidden" structure (and other things) shows up in your teeth. Striations and cracks etc. Wow! Try it!
