QuickGrapher - An Open Source HTML 5 Multi Equation Solver And Grapher
QuickGrapher.com was one of the research projects spun out of Discursive Labs. One of the most promising projects we worked on, it always felt like a project without an intended audience, and it never really lifted off. I’m quite proud of the work that Mark and I did, and think it’s a tremendously cool project.
