I guess I should have seen this coming before (day before). After writing some bits and pieces of math and particle physics code, I realised that the visualiser application is not capable enough to test things. There is a dire need for overloaded key handling and mouse based entity editing and navigation. Also I cannot go on adding buttons for each and every functions, this calls for a JRuby interpreter on the visualiser. Need to spend some time on the gui front to get it up to the mark next.
