[Haskell-cafe] (no subject)

To add briefly to what John wrote, there is a webpage for Yampa:


which includes all of our publications on FRP/Yampa as well as a decent 
release of our latest implementation of Yampa (based on arrows).  The 
release has ample examples of how to use Yampa for graphics, animation, 
and basic control systems such as used in robotics.

Also, although most of the developers have dispersed, I believe that 
most of them are still interested in the ideas, and the 
yampa-users at cs.yale.edu mailing list would probably be responsive if 
anyone bothered to use it.
