[Haskell-cafe] Fran - Functional Reactive Animation

[Paul Hudak]

Actually Pan (and Pan#) are NOT the same as Fran -- quite a bit 
different, in fact.  You may have to email Conal Elliott for a working 
version of Fran, OR you could look at my simplified version (which I 
call "FAL", for "Functional Animation Language") described in Chapter 15 
of my textbook, The Haskell School of Expression.  You can get a working 
version of FAL by downloading the source code from www.haskell.org/soe, 
although I should warn that the graphics lib on which it depends no 
longer works on all platforms and with all compilers.

Another option is to look at Yampa (www.haskell.org/yampa) which when 
combined with a suitable graphics back-end is essentially an arrowized 
version of Fran.  I would recommend this route if you want to avoid 
space-leak problems that are inherent with "pure" Fran.

Let me know if you have any problems.
