Llamasoft is the software company formed by The Yak in 1982. Llamasoft produced games for the Vic, Commodore 64, Atari ST, Amiga and various other machines. Llamasoft games that people might actually have heard of include Gridrunner, Revenge of the Mutant Camels and Llamatron.
Llamasoft still exists, and may yet release The Yak's spare time coding projects "Llamatron.NUXX" and "Sheep In Space II: Ungulate Squadron".
