In the tradition of the thought experiments accompanying Glosses in Hypertext Studies consider symmetry. Compare how quickly can one find the bifurcation point that divides in half the sequence or space formed by the following arrangements.

Hypertextual exploration invites the question: How significant is the signifier?

See especially 1998 gloss http://www.chass.utoronto.ca/~lachance/hyper/gloss2.htm#discussion which invites one to discuss and " Consider a triangle, a square, an octagon. Describe how each compares to the others in terms of reproducibility and transformation according to a set of rules or repeated steps. Which is the most complex shape? The most simple? You might want to use a grid."
