Hi Jamie,

Entirely possible I've not myself yet understood what is needed, but I 
think the mesh will be more of a circle of circles of triangles where 
the latter circles are each split between the left and right "eye-rays" 
assigned to the top and bottom portions of the final image - in opposite 
horizontal directions.

Meaning, the final arrangement of all triangles would - if the circles 
of triangles had some >0 diameter(1) - look more like a cylinder from afar.

Guess I find myself thinking about this, if I can find a round tuit, 
maybe I too will try to come up with an actual mesh.

(1) - Given how loose the ODS approximation looks to be and that the eye 
has some diameter, perhaps this is actually OK?
