MUFFIN can output the event data as VRML-1.0 files. VRML, ``Virtual Reality Modeling Language'' [39] is a file format which can be used to describe scenes which can then be looked at with a VRML-browser. Such browsers are available as so called ``plug-in'' software for many popular WWW browsers. MUFFIN can also add the candidate information to the data, thus allowing to view the results of the calculations in a graphical form and improve and debug the algorithms.
