Polyaboloes, polygons formed by joining isosceles right triangles in edge-to-edge fashion, can also be arranged iteratively to form fractal self-replicating tiles. A particular tetrabolo was used to form these two reptiles, with mirroring between successive iterations employed in the right one.

This weekend would be a great time to submit your art for the exhibition to be held at the Joint Mathematics Meetings. Take advantage of this opportunity to share your work with over 5000 attendees this January in Washington, DC. You’ll need to submit by the 15th at gallery.bridgesmathart.org.

Polyrhombs, formed by joining 60°-120° rhombi in edge-to-edge fashion, can also be iterated to form self-replicating tiles. A 3-rhomb iterates to the same fractal as the envelope of the terdragon curve. Mirroring between successive iterations yields a very different looking reptile (right).

This mixed-media piece consists of an unglazed black-clay ceramic band with two half twists, making it a two-sided object. Steel dowels with long and short ends are spaced along the centerline to define a second band with two half twists, orthogonal to the first.
