Narcisse is an art project by French artist and designer Mathieu Lehanneur. It's a giant bowl with mirrored surface filled with water - as soon as someone comes close to see his/her own reflection (just like Narcissus [wiki]), a promiximity sensor will trigger the interior basin to rotate and deform the reflection.
