David Morgan-Mar (also known as DangerMouse) is an Australian physicist,[1] known for his webcomics[2] and for creating several humorous esoteric programming languages.

[4] Morgan-Mar is a Ph.D. graduate from the University of Sydney, Australia, and has worked on camera, lens, and image processing projects at Canon.

These include Irregular Webcomic!, Infinity on 30 Credits a Day, Darths & Droids, Square Root of Minus Garfield and mezzacotta.

Infinity on 30 Credits a Day is an idea that was developed by David Morgan-Mar in response to a poll he conducted, asking the fans of Irregular Webcomic!

[citation needed] Morgan-Mar helps to produce Darths & Droids as part of a group of eight friends known as the Comic Irregulars.

[10][12] Some of them are full Turing-complete languages while others are simple jokes, often based upon the idea of how a given group (e.g. chefs, orangutans, or necromancers) would be expected to program.

[16] Morgan-Mar is also the author of several GURPS roleplaying sourcebooks for Steve Jackson Games, as well as a regular contributor to Pyramid magazine.
