I'd like you to check this web designer created using Knockout.js, JQuery JQueryui and other cool js plugins.
You can create pages and dashboards using HTML, SVG, 3D primitives (for 3D your browser need to support WebGL and currently only Chrome works flawlessly. Firefox need to enable WebGL in about:config).
Click on "Tutorial" button to watch the clips that shows what you can do with it.
What do you think ?
Any feedback is really appreciated.
