Image Creation Animation (2 Vectors?)

[jinz]

I was wondering, how can you create an image like this. I know that the effect is "Pulse". But do you have to cut out two vectors. It would be great If someone could post a .X3D and/or a.XAR file of this wonderful creation. Or could someone post .X3D and/or a.XAR files, just like this animation please?

P.S I want a .XAR file mainly!
