This is damn good - consider this the most interesting browser-based visual remix tool / toy you will see today:
Created by Felix Turner Rutt-Etra-Izer is a WebGL emulation of the classic Rutt-Etra video synthesizer. The demo replicates the Z-displacement, scanned-line look of the original, but does not attempt to replicate it’s full feature set.
The application allows you to drag and drop your own images, manipulate them and save the output. Images are generated by scanning the pixels of the input image from top to bottom, with scan-line separated by the ‘Line Separation’ amount. For each line generated, the z-position of the vertices is dependent on the brightness of the pixels.

(To run the demo you need the latest version of Chrome or Firefox)
Created with Three.js

Felix also built an audio-reactive version with Processing (video here).
