I just put up a new build of my ODE-based project. It's pretty much feature-complete, just a few bugs to work out before I declare a "v1.0" release. See http://www.natew.com/juice/ for download links, screen shots, and a few words about what it does. In fewer words, Ron T described it as "a visual interface for ODE," and that about sums it up. -- Nate Waddoups Redmond WA USA http://www.natew.com
