Pentram Play Lab

Featuring Inventor Emil Simeonov

Tuesday, August 12
6:30 pm to 7:30 pm
(in person)

Step into a five-sided world of possibility.  Guided by Pentram creator Emil Simeonov, you’ll explore this elegant cousin of the tangram — eight golden-ratio triangles cut from a regular pentagon and brimming with mathematical surprises.  Emil will share the puzzle’s origin story, reveal its links to Fibonacci numbers and Penrose tilings, then turn you loose on a series of hands-on challenges: rebuild the entire pentagon (in more than one way!), experiment with striking non-convex silhouettes, and invent brand-new patterns of your own.  Along the way you’ll glimpse an unsolved question that still intrigues researchers and see how even “wrong” attempts can spark fresh ideas.  Whether you’re a first-time puzzler or a seasoned tiler, come play, create, and discover!
