Cool!

You might want to take a look at Yampa. That's our latest implementation of
the FRP paradigm:

    www.haskell.org/yampa

(Yampa used to be called AFRP, and that name is still used in the source
code in the present 0.9.1 release.)

The release bundle does include a tutorial that was part of the Advanced
Summer School on Functional Programming held in Oxford last summer.

You might also be interested in some of our other publications, see

    http://www.haskell.org/yale/publications.html

In particular "Functional Reactive Programming, Continued" covers some
of the more advanced aspects of Yampa that the tutorial does not get to.

This refers to an old implementation and a rather different style of FRP
from that of Yampa. There is longer any active support for that
implementation.

Hope that helps,

Best regards,
