I would very much like to do something similar, having implemented purely
functional scene graphs on top of OpenGL in OCaml and DirectX in F#:
Immutability is very useful in this area and, in particular, it makes a scene
graph implementation in a functional language much more accessible than
something like Windows Presentation Foundation.
I am now working on a cross-platform GUI based upon our vector graphics work
(Smoke). This can be similarly elegant by referencing purely functional scene
graphs from nodes in the GUI description tree.
I would be very interested to see how this is done in Haskell so, if anyone
does attempt this, please keep me in the loop.
