QLogo-GUI
A UCBLogo-compatible interpreter using Qt
QLogo is an interpreter for the Logo language written in C++ using Qt and OpenGL. Specifically, it mimics (as reasonably as possible) the UCBLogo interpreter developed at U.C. Berkeley. In fact, the UCBLogo manual describes about 99.9% of the functionality. You can find the UCBLogo Manual here: http://people.eecs.berkeley.edu/~bh/usermanual
