Guess what this is (hint: note the cross section)
(If the interpretation is correct, then this is really that shape)
4D tori
From left to right:
3-torus (ditorus) (top: revolving xyz 2-torus, bottom: revolving xyw 2-torus (clifford torus/flat torus))
Toraspherinder (top: glue spherinderal hose into a loop, bottom: glue spherinderal hose in the inside (toraspherinder dual/inside out toraspherinder))
Torinder/toracublinder
Tiger/Toraduocylinder/Spherated bicircular comb
(note the 3-torus made from clifford torus is the same as the Tiger in the projections as the only difference between a clifford torus projection and a duocylinder projection is the presence of a cap at the hole of the torus (the cap is from part of the surface of another bounding 2-torus)
(More cooming soon)
