This is the personal web site of Pelle Nilsson, where I put any of my creations that may be of general interest.

Panta rei (Πάντα ῥεῖ) is a phrase attributed to the ancient Greek philosopher Heraclitus. It means "everything flows", expressing that everything in the world is constantly changing. He said that you cannot step into the same river twice, since the water flow will have changed the river in between. You may see that this is also true of the park at the top of this web site, which will never look the same twice if you reload the page or navigate to another page on the site.
