Getting a CATCHA into yaws is something I have been looking at as well in a 
desultory sort of fashion...

It seems to me that C would probably be the language of choice - the 
selection/response of text for obsfuction part would be straight forward in 
Erlang, but the graphical munginess and distortion/colourbanding of fonts-as-
beziers must be a solved problem in some C library - but which one?

Any thoughts from someone less idle than me would be welcome ;->
