What's that ?
Here is my Web laboratory page where I test some web stuffs.
My tests

It is supported by Safari 2.0 and Firefox 1.5, Deer Park.

 The Fractal Cross [What you will see].
 A fractal cross.
 The Flag [What you will see].
 A sort of flag :)
 A colored fractal [What you will see].

 3D wireframe curves [What you will see].
 Trace 3D wireframe curves from a formula and parameters (ranges, view angles,...).
 3D facets curves [What you will see].

Trace 3D curves with facets from a formula and parameters (ranges, view angles,...). [Other example].
This is just a proof of concept : with some points of view the facets are badly rendered :)
Google Chrome PictureinPicture attack
I opened an issue for a security problem found in Chromium (aka Google Chrome). This issue is private as every security ones but I think I can talk about it as Chromium is not the only browser having this problem and as this problem is not so dangerous.
The problem is a pictureinpicture attack: The "Authentication Required" popup is easily imitable using DHTML. I have created a demonstration of this attack(to test using Google Chrome or Chromium browser).
