This is probably insanely expensive, but it looks really cool: check out The Sky Factory, a company which offers custom-designed “authentic illusions of real skies that transform confined interiors into spaces of natural beauty and freshness.”

I guess when wealthy people can’t install a real skylight, they can buy these to make rooms feel more spacious and open.

The “Programmable SkyCeiling” simulates the rising and setting of the sun.  I can dream, right?!
