>From the web page:

  Vital is a visual programming environment based on Haskell, a
  contemporary functional programming language. It is particularly
  intended for supporting the open-ended, incremental style of
  development often preferred by end users (engineers, scientists,
  analysts, etc.). It may also be useful for teaching Haskell.
