Since it's the 30th anniversary of the world wide web, let me just link to some emulations-in-the-browser of browsers, so you can see some of where it could have gone before we all decided to let Ol' Sociopathic Googly be the entire engine for everything.
Let us all admire that GIF, the greatest GIF that ever GIFfed.

You kids under 40 will have to do some research into that one...
You can't write-protect the World Wide Web, else how Will We Wiki?
