Mirror sphere

[Cashmiir]

What would the interior walls of a sphere made of inward facing mirrors look like?

Take one of those shiny, glass Christmas tree decorations and carefully break off half of it.

It would be very dark...

 

But imagine that you had a light source, and assume the mirror surface is curved.  I think if you were in the exact centre, you would see your head magnified enormously in every direction, but out of focus.  This is similar to the image from a concave mirror at the focus, but of course it would be all round.

 

If you were off-centre, you'd get various other concave-mirror effects, much like looking inside SteveD's bauble.  Some of these are interesting, such as 3-D images which appear to be located between you and the mirror.

 

If I remember correctly how it works, I think you might see yourself in the other half of the sphere, life-size but upside down.

there's a massive one here, well actualy its not really a sphere as the dome is made from straight sided pieces of crystal contructed into the dome shape - but its still vety impressive to stand in the middle of

If you closed one eye, and got the other to the very centre of the sphere, all you would see reflected in the sphere is your open eye.
