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#: http://www.ffconsultancy.com/products/smoke_vector_graphics/ http://www.ffconsultancy.com/products/fsharp_for_visualization/ 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. -- Dr Jon D Harrop, Flying Frog Consultancy Ltd.
