Here's one idea for the library conference group logo, made up in colour.
I changed the chosen design slightly (ha! 'slightly')
I drew it out with the owl spying through the book like in the original design, but then you couldn't really tell it was an owl...
So I'll make up the original chosen design in colour as well.
and here's a real owl, just cause
:)
