For more information and ideas about working with parabola toss patterns of other dimensions you may link to pages written by one of the following math artists:
Danielle, Darlene, Kellie, Jill, Nanyal, Kevin, Rachel, Christina, Jennifer, Candice, Vance, Esther and Melinda.
Most of us are in these pictures but not in order of names.
