Link/Explanation Allied Link History of the Cairo Tiling (from David Bailey) |
Bev
Dunbar and Chrissy Monteleone's photo of "pentagon used to
decorate steps on a veranda in Earlwood, Sydney, Australia, dated about
the 1960s." From David Bailey's extensive site containing many deep analyses of interesting tessellations and their histories. |
Dailey's work with tiling (hosted at ello.co/ddailey and on cs.sru.edu/~ddailey) | ||||||
Generally, in the majority of these, at least, a single tile (shape) is used, but its various orientations are all differently colored. So for example, the concave equilateral pentagon shown in the first row below, has 10 different orientations (each 36 i for 0 ≤ i < 360 degrees). I find this makes it easier to identify subtle differences between tessellations. | ||||||

Link | Showing how to tessellate in an outward spiral (avoiding all but a few hexagonal dominoes) and then replicating the resultant teardrop-pentagon from there. | The clustered teardrop pentagon make some nice patterns, but I'm not sure if it can continue nondeterministically. | ||||
Link | More experiments with a (larger) clustered spiral teardrop. | Link | This particular cluster of half-hexagons forms an 18-sided polygon, which itself tessellates deterministically. | |||

Nice tiling with ektohexagons. It's four-colored (meaning using four orientations) and faultless (meaning having no continued fault-lines -- unlike 'most' tesselations using this tile). | |||
Link Explanation |
An idea based on the L-tetramino. I tried to replicate it along a base-line and to extend upward from there. It repeats horizontally but I am unsure if it can continue upward indefinitely.. | Link and explanation | Tiling with the sixty degree rhombus. |
