Hi there, I developed a PHP animation library with SVG. http://www.svgdreams.com You can pull and watch from: https://github.com/tftr/SVGDreams 1. PHP Classes create SVG shapes and animations, 2. AJAX response can insert SVG shapes, or bind animations to the shapes 3. Send data to the AJAX layer with user event or a system clock 4. Keyboard control I plan to add: 1. Build a collision detection 2. 2d scene and actor control (walk, jump) 3. SVG Filters. Note: You may have problems in IE, I'm not sure it surprises you Best in Chrome and FF. Thanks Tolga
