For the people with biologically lousy facial recognition systems Kotohana has introduced prototype LED flowers that interpret human emotion. The glowing flowers contain little mics that capture voice data. The info is sent it to a processor (a.k.a, the emotion recognition engine) where the results are intepreted and expressed as light. Different tones of voice prompt color gradations and variations in light brightness. Could be hours of fun to use around the unknowing hot-headed jerk in the office. Link.
