Researchers have developed a way to effectively see through walls using interference from approximately 34 Zigbee mesh network transmitters. Zigbee is a commonly used mesh protocol that allows for low powered distributed communications (I have an XBee mesh module on one of my robots).
By distributing the nodes around an area and then monitoring the interference generated by movement the researchers were able to basically see into a room from outside (movement at least). Hmm... I must try this one day :) [via Technology Review]
