Event Driven design tool

Question

Recently I have been experimenting with node.js and I find its event-driven nature very nice. I was wandering if there are any tools for event-driven design, preferably open source. Do you know/use any? Something which would visualize the possible application flow paths would be really good.

Here are a few tools:

• Servoy
• Visual WebGUI
• Maqetta

Servoy is dual licensed, with a commercial license for commercial development as well as an AGPL license for the Eclipse plugin and non-commercial development. Visual WebGUI has a LGPLv2 license. Maqetta is dual licensed as well, with an APL license for commercial development and a BSD license for non-commercial development.
