The Psygnosis "Owl" logo was designed by Roger Dean and used throughout it's lifespan for all Psygnosis productions.
Surprisingly there were over 25 versions of the owl logo.
Every single logo was based on the original artwork.
Some were pixeled from scratch, but most were modifications from existing versions.
I currently don't know why there were so many variations but sometimes a developer would have it's own Psygnosis logo.
Some other time it would just be a color reduced version or just the version that was used during that time or location.
