I love little gadgets for the office and these little guys look real entertaining. Little Robot Friends ($50) are customizable robots that have their own personalities. They can sense the amount of light in the room, hear sound, detect touch and communicate with each other using infrared light. RGB LED lights combined with a 250mW speaker allow them to express their current moods, while settings on six resistor shoe laces give the little guys their personality and affect how they respond to different stimuli. The Kickstarter project is in progress.
