Wow...assuming that's milled from billet, that's some amazing diamond machining.

Very Cool, Imagine how confused someone would be that was looking into that mirror not knowing it's secret.  They would be like somethings different with me, but I just can't seem to figure out whats wrong.  Neat mirror!

I'm not 100% sure that the picture is not doctored.  Seems like the logo is lifted up in the mirror, but is laying flat in the original.  Am I missing something.

The pic is of the spine of the book, but the image should be reversed if it was a flat mirror.

Ok I get it a concave mirror.  You know if you take two concave mirrors and place them on top of eachother so that the mirrors face in and drill a hole in the top, anything you drop down in the hole will appear as a mirage at the hole.  It looks real enough that you can reach out to grab it, but nothing is there.  There used to be a big one at the physics department where my dad worked as a professor.

Yeah, those mirror mirage things are pretty cool. They have mass produced them, but I don't know what they're called. Here's a link:

Only $25, not too bad.
