If one's disco ball is in a cuboidal room, what is the projection of the map reflected on the walls? What if one is in a cylindrical room*? I can't find disco ball in any Snyder index that I have (Geol Survey Bulletin 1532 or USGS Professional Paper 1453).

There's a opening here for an educational disco ball. Who'll be first to get a disco ball and some glass paint? Do we also need a transparent disco ball with a source of light in its centre?

I teach our students about projections with: an inflatable globe that has no colouring for the sea, a sheet of white paper, and an overhead projector. I shine the overhead projector through the globe and hold the sheet of paper against the other side of it. By holding the sheet of paper flat, in a 'tube', or in a cone one can demonstrate several different types of projection. I was very happy with this method, but now I want a disco ball.

Best wishes

This seems like an appropriate Friday Question...Has anyone ever superimposed a Map of the World onto a Disco Ball?

I Really want to know, because if they haven't it needs to be done!

Happy Friday!
