David John Firth is an English animator, writer, musician, actor, voice actor, filmmaker, video artist, and broadcaster. As a cartoonist, Firth's work is largely distributed via the internet, most notably through the popular Adobe Flash animation website Newgrounds and his own personal websites. Several of his works in flash animation, along with multiple music videos and works of video art, have garnered large followings.
Notable animation sequences from Firth include Salad Fingers, as well as the comedic Burnt Face Man series. A number of Firth's works have been featured by the BBC in the UK, and the BBC has hired Firth on several occasions to work on television programmes and commercials. He also created a Flash animation series called Jerry Jackson in which a cartoon character claims to be a professional animator, even though the animation is intentionally poorly crafted. The character was based on Firth's perception of internet users who would leave hateful comments on his videos.
Firth's work often contains a large amount of dark imagery and tends to explore topics of a disturbing or surreal nature, such as depression and mental illness. Firth has stated that it is not his intention to upset or offend. Some of his work may be described as dark humour, while much of it is simply experimental, using many different styles.
In addition to several broadcasts of "Devvo" (in which he is occasionally the cameraman and also plays DJ "Shady Piez"), Firth has produced short films for "Charlie Brooker's Screenwipe", televised on BBC Four.
Firth has produced several animations for the BBC Comedy  web site, including his Musical Predictions 2009 and the Jerry Jackson series in 2009. In 2010 he created a new series for the BBC based around a character called Drillbithead.
Firth composes electronic music under the pseudonym of Locust Toybox. Firth is a fan of Aphex Twin, and has used his music in his work. Amongst other notable influences are Boards of Canada and Brian Eno.
