Excellent. I wonder how practical it would be to put each mirror on a servo so that you can change the image in real time?

I was going to suggest you could use it as a home decoration to make a message everyday but it would only work one day a year?

Awesome! It's like a giant static DLP chip!

This is future of the street art. Mount it using liquid nails to some place that is hard to access and point it somewhere where lots of people will see it during rush hour.

Eg.: You can install it in such way that parliament building will get defaced every day during lunch hours by mounting on near building or tall lamp post. Or maybe put it on your own roof, that way nobody can remove it :-)

I might be getting old but this is the sort of magic by technology I would like to see more of in the world instead of using tech to try putting people into fake worlds in some metaverse.

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.
