EX-STRATA; Interactive Art you can communicate with!


In October 2009 the interactive Light and Sound sculpture EX STRATA #1 (4m / 12ft) was unveiled at the “Homo Ludens” exhibition in Leeuwarden, the Netherlands.

Ralfonso worked for over 3 years with the students and teachers of the following technical Universities/Schools: Hanze Hogeschool Groningen, Noordelijke Hogeschool Leeuwarden, TechnologieCentrum Noord-Nederland in conjunction with the BrainCenter of Philips Light Company, as well with the technical companies listed on the webpage in order to make this interactive Light and Sound sculpture a reality in 2009.

The EX-STRATA sculpture is equipped with led-lighting and speakers. In response to SMS-messages and activation of the distance sensors by visitors, the sculpture produces light and sound patterns. Through a webcam, the EX-STRATA can be viewed and via the SMS function it can be manipulated from all over the world. http://www.youtube.com/watch?v=6OWX2_ksSwU
