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?
Earlier quoted context omitted.
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.
Awesome! It's like a giant static DLP chip!

This one looks a pretty decent size - https://www.sercalo.com/products/mems-mirrors/mm160110-2
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 :-)
