Do you remember when Flash was a thing? I mean, obviously Flash is still a thing, like a haunted stump is a thing, but Flash was creating a Web for a little while there that was more like The Future and less like a phonebook that required thousands of dollars to access.

When we first made this site twenty years ago, Gabe handled all the art and I handled the HTML - I learned how to make a table for just that purpose. But I arranged things in a way that stretched it out because the menu items are all one one side and there was just a fallow field on one side.
