VRML is a program developed by Silicon Graphics. It has the ability to create virtual 3D spaces through which one can travel in. In order to best view this application program a plug-in is needed. Understanding the complexity of this plug-in is another story. Silicon Graphics created the cosmo player which you should download now. Cosmo Software have developed a (somewhat ) stable plug-in called Intervista, I would recommend this plug in particularly.
