Feng Shui Detector

Motorola has patented a Feng Shui detector: "The device houses a camera that checks the colour of the property, a microphone that listens for noise from nearby roads and factories and a compass to find north – a crucial factor for Feng Shui enthusiasts. It can also measure the strength of AM and FM radio signals from local radio transmitters and connect to the nearest mobile phone base station to check for indications of cellphone signal strength."

Perhaps coming soon: a field unit, designed for landscapes – gardens, campsites, caverns... Attachable to airplanes, so the flight can adapt in progress to the most psychologically calming path...
