Disco ball that hangs from your ceiling and projects a 360 degree 3D image which covers your entire room (ceiling and floor as well). Sectors can be allocated to different media or combined for a fully immersive entertainment experience. It also works as a standard disco ball. *cues up ABBA*

Technical question: It's been a while since the 80ies, but in my memory, a disco ball projects fairly small squares of light that rotate as the ball rotates. They're not as small as the squares on the ball, but they're still only covering a tiny part of the wall. |
|
| |
Would you have something that rotates more quickly to use persistence of vision, or would we somehow mentally compose an image from small colored squares, or does the whole thing only sort of look like a disco ball, but project a full field, like a traditional projector? |
|
| |
I assume that this would be more like the old security
camera balls that had 4 cameras in a black ball, except
that they would be projectors. |
|
| |
A smooth mirrored sphere coupled with a standard projector and a carefully distorted image would make this work perfectly. |
|
| |
If you distort it with a lens, you'd also focus the light
correctly. |
