[PD] reactive visualization toolkits

what pd attempts to do with those objects is a juicy area.

theres a number of interesting recent papers on the subject of functional reactive GUIs and/or function-composition based GUI description. ive also seen some good stuff on visualization pipelines. combining all 3 is pretty much the penultimate in this area (most other markets outside of us are only interested in 1-way visualization (Eg you cant change financial market history, you just want to see it more clearly. or one-way 3d rendering from some source timeline/scene for movies/games. professional motion graphics stuff is still almost entirely prescriptive rather than descriptive/reactive, just doing what some timeline says to do) and i havent seen any papers on it yet. ok. maybe fijuu/selectparks stuff?..though that seems more high on fun/cool than theory/design

heres some papers to get your noodle tingled:

Crossing State Lines: (lots on widgets and coming to functional/reactive from an OO world)

it should be noted theyre building their GUI toolkit for FrTime, which is worth reading as well:

TCL can be thought of and used like a Lisp, albeit without fast compilers at your disposal, and resorting to upvalue hacks instead of getting proper lexical scoping for free in Scheme, etc.
