Luis David Garcia-Puente discusses sandpiles, and how they produce amazing "fractal zeroes". Dr Garcia-Puente is an associate professor at Sam Houston State University and was interviewed while attending an MSRI-UP summer program. We'd also like to thank David Perkinson and Cameron Fish for helping with sandpile visualisations.
