Big Red
From PLSwiki
Big Red is an experimental graphical editor for bigraphs being developed by Alec Faithfull. It's built on top of the Eclipse RCP, and so is free and open source software available under the terms of the Eclipse Public License.
Getting it
The code is available in a public Gitorious repository:
git clone git://gitorious.org/big-red/big-red.git
Once you have a copy of the repository, and a copy of the Eclipse Modeling Tools package for your platform, then you should import the repository folder into your Eclipse workspace (File → Import... → Existing Projects into Workspace).
Running it
When Big Red is more complete, a standalone version will be available; for the time being, though, you can run the development version by following the steps above, opening the plugin.xml file from within Eclipse, and clicking "Launch an Eclipse application" (in the "Testing" section).
