Research interests

My inspiration is to ensure that computers are fun to use and make our lives better. In particular, I focus on new ways to interact with data in real-time. I sometimes call this direct manipulation 2.0.

For example, OmniGraphSketcher lets users draw and visually manipulate quantitative data and ideas. And Terafractal lets users interactively create fractals by playing with a visual version of an iterated function system.
