Can we please stop shoving the Legendre polynomials down people's throats? Orthogonal polynomials are some of the most beautiful functions in mathematics; you just need to look at the right domain. And here the unit disc comes to the rescue. Look at the stunning elegance and beauty of this function of Zernike of order 39, and unit azimuthal frequency . Surprise your friends not only with your sense of aesthetics, but also subtlety in choosing a function they can't plot do to mathematical limitations in their software. Customize this shirt but changing the style, the colour or by adding text.
