The University of Minnesota Geometry Center is a mathematics research and education center that supports math and computer science research, mathematical visualization, software development, application development, video animation production, and K-16 math education. The website describes some of their projects that use technology to visualize and communicate mathematics and related sciences. Their software is available for free downloading, along with related documents, research articles, reports, videos of mathematical computer animation, basic facts, and course materials. The Gallery of Interactive Geometry lets visitors compute implicitly defined curves in the plane, explore how rainbows are formed, interact with tilings, and much more.
