Gizmodo highlights the release of Sketch 3D a system you can use to generate 3D anaglyph line drawings in real time.
Built to resemble the familiar Etch-A-Sketch toy this version has three dials. The first two are the traditional drawing cursors. The third one controls the z-axis. This is the depth axis, extending the user-generated content (wire frame line art) into the third dimension. To see the effect in the screen capture below, you'll need a pair of red-blue or red-cyan anaglyph glasses.
