On a Greenport NY intersection I am experimenting with another direction to create 3D objects for the Flanuer Barbican installation at Hack The Barbican.
Within the red cylinder a blue transparent rod appears. In the background beyond the red cylinder a DNA taro leaf spiral appears. In the upper right hand corner of the screen/image three objects are shown captured in this view.
From a position outside the perimeter of the red cylinder the blue cylinder does not appear. Apparently[pun], a transparent 3D object can not be seen within another transparent 3D object. An unrelated second large blue cylinder appears alongside the red cylinder.
