The Fluid tear drop and tunnel meshes with cameras highlighted in pink. The left gives the view through the tunnel which you see is a bent extruded cylinder. You haven't yet seen an image taken from the right camera. The tear shape is a deformed NURBS sphere.
The black pad marks the dense mesh of the observation platform from which I took the second image.

A perspective view of the DysArc meshes shot from upper front left. The arrow marks the Fluid tunnel. There's a shaded model view, too.
