Hey, i found this cool 3D webpage editor called Quantum Hog, which uses the 3DMLW language. Although still in beta version, it already includes source coloring, code completion, file tree view, document tree view, fullscreen view, some functionality in WYSIWYG editor etc. Btw it's also free to use
and really simple. If anyone has tested it, please let me know what you think about it.

btw, does anybody knows hoe to create 3D web animation? there are lots of programs available, but they are heavy (file size is big) and it is not easy to upload and download it on a web page?
