“Sewn Shut I: Boy's Surface in the 3-sphere ”
2008, 3D printed model, 8 cm tall
An immersion of the real projective plane in the 3-sphere, with several disks removed along the loop of self-intersection and 2-fold rotational symmetry.
“ Sewn Shut II: Another immersion ”
2007, Fused deposition model, 15 cm tall
An immersion of the real projective plain in 3-dimensional euclidean space, which is not ambiently isotopic to Boy's Surface, with several disks removed along the loop of self-intersection.
“Boy's Surface in the 3-sphere ”
2008, Digital print, 40 cm tall
An immersion of the real projective plane in the 3-sphere, with the loop of self-intersection removed and 2-fold rotational symmetry.
“Another immersion in the 3-sphere ”
2007, Digital print, 40 cm tall
Another immersion of the real projection in the 3-sphere, which is not ambiently isotopic to Boy's surface and has 2-fold rotational symmetry.
