The Ukraine company HoleRoll has these ace blackout blinds for windows.  Through (I assume) laser cutting fabric and material, you get a gorgeous shadow/lightbox view of either the Manhattan Skyline, the London Skyline, or the general night sky.  Unfortunately, the prices are quite high – $178 for one pane of the panel.  That’s the base price, before you put measurements in and choose other options.  I can tell you this much, I’m not about to spend over $500 on window shades – for a single room.  They look high quality, I bet I could make my own though.
