I invite you all to read this cool article about the number five, pentagons and poetry.

Helaman Ferguson's unruly hyperbolic quilt, sewn together from pentagons of cloth, refuses to lie flat.
In his artwork Hyperbolic 5, Ferguson has created a particularly striking representation of the hyperbolic plane. It shows necklaces of pentagonal tiles going around a central pentagon in alternating gold fives and mirror images of gold fives. The gold "5" is a reference to a famous painting by Charles Demuth (1883–1935) called The Figure 5 in Gold. Demuth's painting was itself inspired by an imagist poem, "The Great Figure," by his friend and colleague William Carlos Williams (1883–1963).
"My particular inspiration for Hyperbolic 5 was both Williams and Demuth, especially Williams," Ferguson says. "Somehow I felt Williams' verbal images were even more powerful than the painting." A QuickTime video clip presenting Williams' 1928 poem "The Great Figure" is available at http://www.learner.org/catalog/extras/vvspot/video/williams.html.
