Golan Levin

Golan Levin is an American artist who currently lives in Pittsburgh and is a professor at Carnegie Mellon University. He describes himself as someone who, "develops artifacts and experiences which explore the expressive use of computation". By designing works that focuses on "manipulation and performance of simultaneous image and sound", he is able to engage and stimulate viewers as they watch and interact with his pieces through numerous senses. He allows a relationship between the viewer and piece to grow as a way to abstractly analyze our relationships with one-another. 

One work that caught my eye was a performance from 2003 called Messa Di Voce. The piece, "augments the speech... touches on themes of abstract communication, synaesthetic relationships, cartoon language, and writing and scoring systems". Through a whimsical mean he is able to reflect on and translated our forms of communication into a visual experience as well as an auditory one.

Footfalls (2003) is piece that was derived from Messa; by utilizing the balls that the performer once interacted with, Footfalls allows the audience to interact with the technology in both a personable and instinctual way. The project works through "stepping and stomping sounds produced by the visitors' feet [which] are detected by microphones under the floor, and used to govern the size and number of virtual objects that fall from a six-meter high projection. The harder the visitors stomp, the more items fall. Using their silhouettes, visitors can then "catch" and "throw" these projected objects around".

Levin also keeps a Blog where he writes about new steps in technology (ie. 3D Printing flutes and such) in both artistic as well as just general contexts. I thoroughly suggest a look through.
