“act of a flowing; a continuous moving on or passing by, as of a flowing
stream; a continuous succession of changes”

A graphical live coding environment for Scheme.

This release is the result of a partial rewrite of fluxus to allow it to
be extended and used more flexibly in the future. Part of this work was
to integrate it with PLT Scheme (www.plt-scheme.org) which means we can
now start to use it’s impressive Scheme editor (DrScheme) for writing,
live coding and debugging fluxus scripts.
