Visi is a new language... a "what if Haskell and Excel" had a love-child kind of language.  Visi is pure, lazy, just like Excel, yet Visi is statically typed, like Haskell.  Visi's syntax is beautiful, in a Haskell/Python sort of way, yet inviting to spreadsheet users.  Visi is targeted as a HyperCard-like language for the iPad and the cloud, but with a firm grounding in computer science that has evolved since the mid-80s.  Visi is built in Haskell and takes advantage of the GHC platform.  David Pollak, the inventor of the real-time spreadsheet, founded the Visi project which can be found at http://visi.io
