Penguin Software
From CPCWiki - THE Amstrad CPC encyclopedia!
Penguin Software was run by Pixel, and was well-known for a small, but well executed collection of AMSDOS PD, and an elegant A5 paper catalogue. Its most popular works were Animator demos and the Amiga Graphics collections, both put together by David.
After David's death, Penguin was briefly restarted by Simon Green.
