[Haskell-cafe] Visualizing Typed Functions

I saw a visual scheme for this purpose at FDPE'08. It uses an  
alternating colouring scheme, representing arguments as holes: a hole  
in a black thing is white and a hole in a white thing is black.

I only found an ACM link: http://portal.acm.org/citation.cfm?id=1411272
