The Sphinx Sums a Geometric Series
This is a short, animated visual proof demonstrating the sum of the infinite series with first term 8/9 and ratio 1/9 using a famous rep-tile shape known as the Sphinx. Geometric series are important for many results in calculus, discrete mathematics, and combinatorics.

This animation is based on the fact that any rep-tile leads to a geometric series sum visualization and the Sphinx is a famous rep-tile, which you can learn more about at en.wikipedia.org/wiki/Sphinx_tiling
