The London Haskell user group has a talk next week:

The Algebra of Algebraic Data Types

Speaker: Chris Taylor

Haskell's types are "algebraic data types". But what's so 'algebraic' 
about algebraic types? This talk explains what types have to do with 
algebra, starting with counting and type equations (Maybe x = 1 + x) and 
maybe getting as far as the calculus of types, divided types and what 
the hell it means to take the exponential of a type. No assumptions on 
any maths background beyond what you learned at school.
