Successfully turned on GEANT4 visualisation in MAUS using datacard parameter:

geant4_visualisation = True

.wrl files produced.

VRML viewing very poorly supported in Linux. Found an application called MeshLab, which works on Ubuntu 12.10, which works with the output .wrl files and is available in the Ubuntu repositories. Other options such as OpenVRML, FreeWRL, view3dscene failed to compile or otherwise did not work (see http://cic.nist.gov/vrml/vbdetect.html for a list).

MICE geometry from the files is displaying fine in MeshLab (see attached), but not particles, which I would like very much.
