Moon Ribas

In 2013, Moon developed a sensor that vibrates whenever there's an earthquake in the planet.[13] The sensor, which is permanently implanted in her feet, vibrates in different levels depending on the intensity of each earthquakes and is wirelessly connected to online seismographs, which means she can feel earthquakes from all over the world regardless of where she is.[14] Moon has been wearing the sensor permanently since March 2013 and has used her seismic sense to create dance pieces.[15] Waiting for Earthquakes is a solo dance performance where the dancer stands still until an earthquake is felt. The choreography depends on the earthquakes felt during the duration of the performance and the intensity of the dancer's movements depend on the magnitude of each earthquake (which can be felt from 1.0 in the Richter Scale). If there are no earthquakes during the time of performance the dancer will not dance.[16] The piece was premiered on 28 March 2013 at Nau Ivanow, Barcelona.[17]

Moon's first sensory experiment was in 2007 when she created and wore a pair of kaleidoscopic glasses for three months.[18] The glasses only allowed her to see colour, no shape. The lack of shape perception increased not only her sense of colour discrimination but also her detection of movement. Any slight change of colour in her field of vision indicated that something had moved.[19] During the three-month period, Moon visited several cities in Europe and met people without ever seeing their faces.[20]

In 2008, Moon created a speedometer glove that allowed her to perceive the exact speed of any movement around her through vibrations on her hand. She wore the glove for several months and was able to sense different speeds depending on the vibration intervals.[21] She later transformed the glove into a pair of earrings that vibrated whenever there was presence around her.[22] Moon travelled around Europe with her speedborg earrings to find out what the average walking speed of citizens was in different cities. The Speeds of Europe is a video dance that shows the results of her research; Londoners and Stockholm citizens for example walk at a similar average speed of approximately 6.1 km/h whereas people in Rome and Oslo walk at an average speed of 4 km/h.[23]

By 2009, Moon was able to detect not only the exact speed of any person walking in front of her but also her own speed.[24] Knowing her own speed allowed her to create Green Lights a piece choreographed in relation to a set of 8 traffic lights: by learning the traffic light timings of Barcelona's Rambla de Catalunya avenue and by measuring the distance between each traffic light, she calculated the speed she had to walk to avoid red traffic lights and was able to get from one end to the other end of the avenue without stops.[25]

In 2010, Moon explored the possibilities of sensing movement behind her by turning the speedborg earrings around.[26] The earrings were developed further by students from La Salle (Barcelona) by adding 4 extra sensors in order to gain 360° perception of movement through vibrations around the head.[27]
