Community Collage
Many-Sided Circles debuted at Andrea Guskin’s Local Roots Project event at the San Leandro Main Library on Saturday, the 13th of December, 2025.
Many-Sided Circles is an ongoing, community collage practice open to all. Individual, community-made collages are arranged to form larger compositions. Specifically, regular isosceles trapezoids are placed side-by-side to create ‘circular’ polygons such as the regular-hexadecagon rings pictured below.
[On the left] a regular-hexadecagon ring comprising sixteen regular isosceles trapezoids.[On the right] a three-ring regular-hexadecagon comprising 48 isosceles trapezoids (sixteen each of three sizes). This sample shows 23 of the 48 components “collaged.”
How many sides are needed for a polygon to appear or behave like a circle? If the illustrations below were physical objects, which among them could roll?
There is an analogy in the frame-rate of motion pictures. A frame-rate of fewer than 8 frames per second fails to produce the illusion of motion. Around 10-12 frames per second, the illusion becomes compelling, and by 16-18 fps, it’s entirely convincing.
