The crown as made in Xara3D is not a spinning crown, as Xara3D only allows one animation type to be used in any single file, and I need the ripple animation to position the various parts correctly. I acheived the spin by taking several single images from Xara3D while changing the viewpoint in regular steps, thus building up the spin animation in XaraXtreme, and exporting an animated gif from there.
