OMG - prayer rug with built in directional indicator, what will they think of next Abdul?
Carpets with magnetic compasses in them......
Gives me some ideas.....
Universal prayer room featuring a large cross up front, and completely enclosed in faraday cage so that phone maps and such will not work. Emergency wall phones provided to allow for emergencies.
Varying electromagnetic fields in the floor that cause the compasses to all point towards the cross which would be at least 45 degrees away from Mecca.
The message - all compasses lead to Christ!
