Mr Screen

The circular light fixture from Pink Floyd shows.

30 intellilights around the rim, by the P.U.L.S.E tour it was moveable from vertical (circular screen behind stage) to horizontal (halo over Gilmour). Maybe 10m diameter?

From wikipedia: A large circular projection panel dubbed "Mr Screen" first made an appearance during performances of Dark Side of the Moon in 1974 and became a staple thereafter. Specially recorded films and animations were projected onto it, and for 1977 "In the Flesh" and 1980-1981 "The Wall Live" tours, coloured spotlights were fixed around the rim, an effect which reached its zenith with the dancing patterns of multi-coloured lights in the A Momentary Lapse of Reason and Division Bell tours. In the latter, the screen could be retracted behind the stage when not required, and was tilted with its peripheral lights focused onto the stage into a single spotlight during the final guitar solo in "Comfortably Numb".

So, could we make one for a home theatre?
