My alma mater (I always feel a little weird calling the place where I learned a ton of facts the mother of my soul – certainly there have been more formative presences in my life!) has set up a pretty neat display of how physics, computers, and precision machining can create beauty: prima facie unremarkable mirrors that create pictures by reflecting sunlight onto concrete. It’s worth the two minute video, though the first ten seconds will give you a good idea of what it looks like.
I finally made time to watch this — thanks!
You’re welcome!
