While searching for a design tool for Haskell, I've come across the PhD thesis of Dan Russell
He also mentioned the tool in cafe some time ago: http://www.haskell.org/pipermail/haskell-cafe/2003-June/004606.html
Does anyone in the cafe, or himself, direct me to the download link of this tool; so that I can try it out.
Cheers,
