Rapicorn is an experimental UI toolkit.
It aims at bringing UI-design, UI-notation and UI-programming as close
together as possible. To accomplish this, it provides conscise ways for
UI notation, usable also throughout design phases.
Simple but powerful programming mechanisms will be provided to automate
binding of programming and GUI logic and to minimize manual work.

The project is hosted at:

A mailing list is available at:

A tutorial, technical writings and more is provided at:

As an experimental toolkit, many design aspects of Rapicorn are
far from finalized. Feedback is very much appreciated, allthough
many things provided by mature toolkits, such as complex composite
widgets, thorough documentation and language bindings are still in
the works or have yet to be started.
