Via Pink Tentacle 

KOTOHANA is a flower-shaped terminal which allows to remotely communicate human emotions using LED light. LEDs change color according to the emotions felt by the remote person. Emotional state of the remote person is inferred by analysing affective correlates of voice; results of the analysis are sent via wireless LAN to the other terminal, where it is expressed as LED light. KOTOHANA is a joint project of NEC, NEC Design and SGI Japan
