Llamasoft

Jeff Minter (born 22 April 1962) is an English video game designer and programmer who often goes by the name Yak. He is the founder of software house Llamasoft and has created dozens of games during his career, which began in 1981 with games for the ZX80. Minter's games are shoot 'em ups which contain titular or in-game references demonstrating his fondness of ruminants (llamas, sheep, camels, etc.). Many of his programs also feature something of a psychedelic element, as in some of the earliest "light synthesizer" programs including Trip-a-Tron.
