I took a rotating spheres.x3d file I had previously written and used it to replace an x3d scene in an example x-ite scene. I was surprised that the animated spheres scene. ,with all of its nodes and fields and protoype (created) nodes, displayed without modification. The display works in a separate window so as for the exploding cube, use your back button to return to this wordpress post. I also note that x-ite provides a wordpress plug in and at some stage I will have a look at that.
