re: #9 CuriousLurker

This is real. Jews have a concept similar to prayer rugs, but no one would know about it. We’re supposed to pray in a space ‘4 amos X 4 amos’. It’s a square (obviously), about the size of a prayer rug, and we don’t do the full prostrate but once a year.

I’m sure that if someone could find a way to market invisible space, they would.
