<h1>My first animated and textured WebGL content.</h1>
<p>
Finally my first small steps in the new world of WebGL. It is
pretty cool to have hardware accelerated, animated 3D objects
in your page.

<h2>Hidden on purpose.</h2>
<p>
This paragraph is hidden on purpose to see how the transparent
background of the GL canvas behaves if positioned above another
element. Now, we just fill in some stuff to get the paragraph
filled with some more stuff. Eventually we will have so much text
that it becomes big enought for the height of the GL canvas. Well,
as the canvas is transparant at least the maximum height of the
cube.
