Ping Pong Projector Beam

Here is a bit of a weird question, perhaps, but I have been thinking about a very clever installation I saw in the Asia Society on Park Avenue in NY.

I noticed when we checked in for their exhibit that over the receptionist there were these really slick, high tech paper thin looking projection screens, suspended in space where there was no apparent projector in sight.

Well it seems that this was generated with a fairly ordinary LCD projector, and then BOUNCED off a mirror hidden under the desk.

So my question is please:

Can I "bounce" an LCD beam off a simple mirror like this for a home theatre application?

Would some high end, optical grade mirror work better? Or a particular specification for this application?

Any other thoughts or considerations?

I would like to set up TV at my office and home theatre at home where the projector was NOT visible, so your suggestions and input are greatly appreciated.

Best
