Become a mathematical accuracy activist in your own home through the medium of branded apparel with this t-shirt, inspired by Matt's campaign to change the stadium symbol on UK road signage into a football that is actually geometrically possible (in our universe, at least...). "Say No To Mathematically Impossible Street Signs" today!
An even more spectacular version of Matt's rant about geometrically impossible footballs can also be seen as part of the new Festival of the Spoken Nerd stage show, You Can't Polish a Nerd, available on DVD and as a luxury download pack.
Printed using environmentally friendly inks and renewable energy on organic, sustainable, fairtrade cotton t-shirts by Teemill.
