What is Gallifreyan?

Gallifreyan is the fictional language of the Time Lords, from the TV show Doctor Who. On the show, it's usually just random circles. I'm not affiliated with Doctor Who or the BBC, but back in 2011, I created a "Gallifreyan" writing system. It somehow got really popular among fans and eventually made its way onto the show. I haven't been very active in the Gallifreyan community, but they've produced so much absolutely brilliant work and never cease to impress me.
