The Conlang Flag, a symbol of language construction created by subscribers to the CONLANG mailing list (a mailing list for discussing constructed and artificial languages) which represents the Tower of Babel against a rising sun.

The colours represent creative energy, and the layers of the tower imply that a conlang is built piece by piece, never completed. The tower itself also alludes to the Tower of Babel, as it has long been a tradition to demonstrate a constructed language by translating the Babel legend. The Conlang flag was decided on by a vote between many competing designs, and one of my own contributions to the conlanging world is that I was the person who facilitated this election. The winning design was drawn by Christian Thalmann, who introduced the layers. The idea of including the Tower of Babel on the flag had been introduced by Jan van Steenbergen, and the idea of placing the sun on the horizon behind it by Leland Paul. The idea of having the rising sun on the flag had been introduced by David Peterson, who saw it as representing the rise of conlanging from obscurity to popularity and notoriety.
