Sierpiński Carpet Project

If you enjoyed the magnificent ridiculousness of Matt Parker’s MegaMenger international fractal building project, but would prefer something slightly lower-dimensional, we’ve found the collaborative international fractal-building project for you!

A team led by José L. Rodríguez at the University of Almería, in Spain (who also built a Menger Sponge for MegaMenger) are attempting to build a giant Sierpiński carpet, using green and purple stickers, and an army of unwitting excited school children.

Matt Parker’s Fractal Christmas Tree

Stand-up Mathematician and all-round maths lover Matt Parker has been busy again, and he’s made a set of free worksheets for teachers (and, of course, interested non-teachers) to assemble paper nets of 3D fractals, including a Menger sponge and Sierpinski tetrahedron (which I’ve just learned is also called a tetrix).

There’s also a sheet for making a delightfully festive/mathematical fractal Christmas tree, with a Menger sponge base, Sierpinski branches and a Koch Snowflake star on top. Presumably those interested can make Mandelbulb ornaments and Cantor Set tinsel to hang on it. Don’t ask me how that would work.

The worksheets can be downloaded from Matt’s Think Maths website.

Anyone who successfully builds the whole thing: send us a photo and we’ll post it here. Jokes about fractals taking a while to cut out/paint in the comments.
