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. See more at http://people.reed.edu/~davidp/ and have a play at http://people.reed.edu/~davidp/web_sandpiles/
