Stelo is dedicated to Jacques' brother's little granddaughter, Maïlou, who died suddenly in 2006 before her third birthday. Stelo means "star" in Esperanto, and a real star visible from Earth has been named Maïlou in her honor. The puzzle's star shape is also in remembrance of her star.

The 12 Stelo pieces are a simpler subset of Poly-Spidrons, consisting of the order-3 pieces without the Spidron curves. Each tile consists of six 30-60-90 triangles paired as either equilateral or isosceles. The four transparent colors identify the structure of each tile by its component subtriangles. The tray is about 5½". See Jacques' page for more explanations.

A wealth of challenges await the puzzler. Jacques has supplied a collection of 229 beautiful shapes in silhouettes that are little artworks in their own right (a few samples appear below), and more may be added from time to time. Feel free to download them from his site to go with your Stelo set. And if you find new shapes, send them to Jacques and add your star to this galaxy.
