How to Make Sisp


Now it's time to learn how to build a swirlprism. First we would need to obtain access to a four dimensional world and get the poster board, 4-D scissors, coloring pencils, glue, and other useful 4-D items - I'll let you figure that one out :). Sisp is the first swirlprism found, discovered by George Olshevsky.
Sisp Piece Sisp StrandSisp coming together

Above is the piece type of sisp, followed by a strand of ten and then three strands folding together (which can't be cut out of poster board like this), they were created using Stella4D. We could name the piece and combo as follows:


the One Piece Type

Cog - magenta piece - comes from the sides of the pap cells, 600 needed.


the One Combo

Zipper - composed of ten cogs, folded outwards and glued together at the ends to form a ring, - magenta, 60 needed.


Building Sisp

Put convex tabs on half the equalateral triangles of the zipper in an alternating method and concave tabs on the inside triangles on the left side and concave tabs on the concave pentagons on the right side. Now "zipper" three zippers together from the inside faces of the zippers with concave folds. This will make an indented zippered triangle like twister of which 20 are needed. Put these together like they were a gad-twister. The model is now complete. Toss it in the air and swirl it before catching it.
