Jos Leys makes great math movies, including this gem of a metaphor:

I can’t wait to use his Mobius Bloom’s footage to strengthen the point I’ve been trying to make – that the Creating tasks are not for advanced students, gifted people, or graduate school only! Actually, struggling students, young kids and noobs need Creating tasks much more.

There are always jobs for kid, teen and grown-up interns at Natural Math. You help the world, develop valuable skills, and enhance your portfolio. What’s not to love?

I was too slow to buy the limited edition, but I really admired the thoughtfulness and deep knowledge of “who’s who in math entities” that went into designing it. It’s a list of topics for two-three years of a good math club meetings, right there! Including the Mobius strip, of course.
