I just downloaded it and started playing with it. Thanks for the link!

First impressions...
  • I'm not a Java fan...
  • The design side of the program has some nice features, such as the fin editor.
  • The side view is nice and clean. I think I like the layout of the text data within the view a little better.
  • The program is obviously inspired by RockSim. The general arrangement of the screen elements is the same.
  • I do like the illustrated buttons in the component selection section.
  • There is not a database of pre-defined components, so each time you create a design, you have to feed the dimensions into the dialog for that component.
  • The version I downloaded (0.9.3) has no motors defined, so you cannot run a simulation.
  • I like the graphic simulation of components that RockSim only hints at with "(M)" symbols. The dashed rectangles provide a better visualization of where the component winds up inside the body tube.
  • The saved rocket files have an interesting three-letter extension -- ork, for Open RocKet...

The program has a long way to go, but I think the developer is on a good path. If he would change the program from an interpreted language (Java) to a true compiled language, such as C++ or Free Pascal & Lazarus, the program would run faster; it would still be cross-portable to Mac, Linux, and Windows machines using a compiled language, it just requires multiple binaries. Not really an issue.

I'll keep an eye on it, for sure.
