bullet The Haskore music system (and other DSLs)
Paul Hudak at Yale has defined a powerful language for describing musical structures in abstract terms based on Haskell (see the Haskore Project website)

In general, Haskell's abstraction features make it ideal for defining domain-specific languages as Haskell libraries

bullet The Fran and Pan graphics projects
Conal Elliott at Microsoft Research has developed a couple of libraries, Fran and Pan, which allow a very high-level way to specify complex graphics, animations and interactive animations

In Fran, for example, an interactive, single-player "Pong" game can be written in less than 20 lines, using concepts such as integration to express the relationship between velocity and position

bullet GUI projects
A number of graphical user interface libraries are listed on the Haskell home page, ranging from low-level interfaces to traditional C libraries, to high-level, purely-functional characterizations

(see the GUI library section of the Haskell homepage for more details

bullet The Galois Connections ray-tracer
Every year the International Conference on Functional Programming holds a 72-hour "challenge problem" contest; last year's problem involved writing a 3-D ray-tracer which compiles a scene-description language into rendered output

a local team from Galois Connections managed to achieve 2nd-place standing for their entry
