  This is quite a bit different. DLP like projectors are binary: straight forward or somewhere away. The layout of the grid of mirrors matches the layout of the dots you can illuminate, in the image. Something like OP has would require some pretty serious angular precision.

    You could use holography/beamforming to steer a beam from a DLP, although it would be just a small % of the original power.

      I think the beautify of the mirror system is that it's direct, understandable/observable, and nice to look at by itself, even if it's not showing an image. It's elegant. If you use beam formers and DLPs, you're just making an overcomplicated DLP projector that's going to look like an overcomplicated DLP projector.

        Absolutely. And it'll keep working on a sandy beach far from any power source.
