Astro-Art

The emerging field of bio-art begs the question: what other science/art "mashups" are possible? What would astronomy look like if taken over by artists? Can we track space junk and use it as a projection medium in the manner of Ken Perlin's holodust? Can we launch satellite arrays, using each satellite as a pixel that turns "on" when it orients itself to reflect the sun towards Earth? Pauline Oliveros has already improvised with moon, can we improvise with Sun by bouncing sound off its corona? What more distant interactions and displays are possible?
