You talk, and EtchASound makes your words into 3D sketches – “EtchASound is an installation inspired by the world famous toy Etch-A-Sketch. By interacting with EtchASound audiences can have the unique experience of drawing with their own voice. First the user creates a 2 dimensional image in real time with his or her voice, and after a few moments the computer converts this into a 3 dimensional drawing. Then when you wear anaglyph glasses (3d red and cyan glasses) users can see in real space the drawing that you have created.” [via] – Link. & process of EtchASound (photos).
