My girlfriend and I have a circular bed, filled with about 15 pillows, with Morroccan and Persian designs. We also have uber nice silk sheets and low watt lamps, and thick curtains.
We've tried to make it as... Asian east meets Middle East/Northern Africa, with some french opium den highlights, such a the fleur de lis curtains. It really makes the experience, and is so comfortable that sometimes neither of us can get motivated enough to get out of bed and clean the hookah, so we leave it until morning.
And the black light sounds interesting, we'll have to try it!
