Note that the image of the “Henrici cubic” with three cusps above is a MO-Labs computer rendering and not a photo.
n the 19th century, Olaus Henrici constructed a model of a quite symmetric cubic surface. This is a modern variant of it, allowing also to look “inside” of it from the bottom (which was filled with support material in the 19th century version). This is a very interesting aspect in the case of this model because one can now “look inside” the “bubble” in the center of the object.
June Barrow-Green gave a nice talk on Henrici and his models at Oberwolfach. A pdf including her brief article on Henrici’s model is online.
