Hi, I try to figure out how much work it would be to create such a page: http://tiny.cc/2c8odx

I know that the page is build in:
-HTML5 Canvas
-JavaScript
-CSS3

It would be great if someone can make a assessment about the difficulty of the project for a coder who is skilled in this languages.

The question refers to the presentation (universe) not to the intro and content of the page.
