Unworthy of lasers
Give them technology, and this is what they use it for:
All mosques have a niche showing the direction of the most sacred Islamic site, the Kaaba, an ancient cube-like building in Mecca's Grand Mosque.
But people looking down from recently built high-rises in Mecca found the niches in many older mosques were not pointing directly towards the Kaaba.
Some worshippers are said to be anxious about the validity of their prayers.
There have been suggestions that laser beams could be used to make an exact measurement.
