There are dantonag.it
The story behind it.

Are there really infinite dantonag.it?
I always wanted to do a website that changes every time you visit it.
But maybe I'm far from it. Infinite is slightly bigger than you may think.
The frontpage of dantonag.it is generated each time from a string like 0x1a345239039.
That number contains the effect variables, the seed for 3D model generation, and so on.
Additional variation parameters are given by an UTC timestamp.
So, in theory, you should not see two identical dantonag.it.
Until 2038, at least.
