October 6th 2013, National Mad Hatter Day! It's always fun to go a little mad; giggle, dance, add too much sugar to your tea. In 1986 some computer-folk in Boulder, CO celebrated a general day of silliness, inspired by the drawings of the Mad Hatter by John Tenniel in Alice In Wonderland. It was announced that year on computer networks, becoming more popular as people realized its value. Mad Hatter Hat (by J Ferwerda)
