It's pretty involved. It has bipolar, linear3D, post_curl3D,curl3D, bwraps7, cannabiscurve_wf, bilinear and roundsphere3D. Are you going to try doing it? Setup the linear3D in fours like you were doing a tileing, but don't tile them. Start with bipolar. Put another bipolar after the linear3D's That should get you started. The rest is up to you!
