Personalized Lissajous curves can be found at this Wikipedia link: http://en.wikipedia.org/wiki/Lissajous_curve In case you want to add some extra information, here is a brief explanation of what Lissajous curves are - they are figures created by plotting the parametric equations of oscillation of two sinusoids with different frequencies and/or phase shifts. They are named after their discoverer, the French mathematician Jules-Antoine Lissajous. These curves can be customized to display a wide range of visual patterns depending on the frequency and phase settings of the sinusoids.
