With a rotating star light projector?

[N.047275576]

The stars projected a further distance will move faster along that surface and the stars projected to a nearer surface will move slower along that surface. The projector, you see, is moving them each by the same angle as measured from the projector, and the more distant surface has to have a greater length to achieve the same angle. So if the ceiling is lower to the projector than the distance from projector to the wall, what you described will have to happen.

Reading what you wrote makes me feel like some kind of scientist, huh. You could simply say that this star light projector would be a really cool addition for your room, I’m just reading about some distances, who needs this, I’ll put it more simply, you want to decorate your room and make it more comfortable and more Vibe, come in and choose a project like this for yourself, a really cool design solution.
