Abstract
A mobile geometrical form having two helical sections interdigitally wound into each other about a common axis. The helical sections are of substantially the same radius and are out of phase with respect to each other. Each end of one helical section continues into a twisted loop, which in turn continues into the adjacent end of the other helical section to thereby form a unitary structure. The geometrical form is comprised of a double sided continuous strip of material. Optionally, a tube axially extends through the helical sections and serves to anchor the loops at either end in spaced apart relationship, while permitting translatory motion of the unitary structure therethrough.
