Fact Triangles was an application to practice multiplication and division facts. It was a project that Eric started for Alex when Alex was in 3rd grade and in late 2007 Alex took it over and made some major improvements (PPC-Intel Universal binary and true Tiger and beyond support as well as self-updating features, not to mention publicly releasing it). Though it hasn't been actively developed for years, we keep reference to it here as an example of our early work.
