Bartosz truly deserves to be more widely known.

His Category Theory for Programmers book is an excellent introduction to the CT world if you come from a Computer Science background (well ... duh it says it right there in the title) and know very little math.

Highly recommended to give it a try, even if the topic doesn't seem to fit you. This is one of those books that will make you a better programmer regardless of what you do.
