Both Blender and Maemo have python. So it is potentially possible and potentially not so hard to make N900 3d blender controller. All we need is python modules for: 0. Recording accelerometers data on N900; 1. Streaming accelerometers data live to desktop and caching it real-time; 2. Controlling active blender view; I suppose it will be: a) active only when holding some button (camera for example), and b) turning blender view relative, not absolute.
