3M to showcase a micro-projector

Any idea what kind of range this would have. Specifically I am thinking of an application where it would have to project from ceiling height to the ground, 2.5-3.0m.

The projected image can be small, 30x30cm, or perhaps less. If the zoom is fixed then an after-market lens can be attached.

Secondly, what would be the expected weight, raw (without any packaging), and power consumption?

That's ok, 300g is too heavy for my application.

The idea, was to have this mounted to the flying robots (like a fancy RC helicopter) I'm working on. I need a way of project an image or a light source on the ground. Lasers work, but the spot is too small to be visible appropriately. Focused 3W LEDs aren't focused and bright enough to be usable.
But a mini-project would be awesome if it was bright enough for the computer vision of other robots.

Still, somethign I will keep an eye on.

yeah, but then the actual brightness reduces massively. Lasers are only bright because they are so tightly focused.
