Granted, the custom installation is of a "if you have to ask, you can't afford it" price, but what price isn't worth having the molten pinks and reds of sunrise or sunset splayed all across my place of sleeping/working/eating. Think of all the electricity saved by using natural light! And at night time, it switches over to halogen lighting, to make sure I don't end up solely in the glow of my computer screen.
Alternatively, it also makes a great trap for unexpected vampires.
