Ubuntu/Fedora/Mint/Debian/Chakra/CentOS/OpenSUSE and Linero is supported. Free support in the discussion forum. See Snowmix in action on Youtube http://www.youtube.com/user/Snowmix4video
System dynamics program with additional features for economics
Minsky enables the simulation of models (particularly from economics) defined in terms of coupled ordinary differential equations. The models are defined using a drawing canvas (rather like VisSim), and a double entry bookkeeping system known as a Godley table.
Ayam is a free 3D modelling environment for the RenderMan interface.
CECILIA is an environment for music and signal-processing that uses Csound as its underlying audio processing engine. One can think of CECILIA as a completely programmable sound-processing tool, with real-time interactive processing on soundfiles or live
