A new version of yampahttp://hackage.haskell.org/cgi-bin/hackage-scripts/package/Yampa-0.9.2was uploaded to hackage today, but it's website http://www.haskell.org/yampa/ hasn't been updated since 2004. SpaceInvadershttp://hackage.haskell.org/cgi-bin/hackage-scripts/package/SpaceInvaders-0.4...depends on HGL and Yampa. There's been more noise around Phooeyhttp://haskell.org/haskellwiki/Phooeyand TV http://haskell.org/haskellwiki/TV in recent months, but afaik, hasn't been used for any applications yet. There was also ParseP http://twan.home.fmf.nl/parsep/ which seems to tackle a similar problem, but from the perspective of a more general parsing library. Are there other purely functional reactive libraries in active development? Why might one choose one over another? Thanks, Greg
