Turtle Tracks

Turtle Tracks is a modern Logo interpreter and runtime environment written entirely in Java. It is not a direct port of an existing interpreter, but written from the ground up specifically for Java, and designed to take advantage of the strengths of Java as a platform. Turtle Tracks is platform-independent and Internet-ready, and supports numerous advanced features such as multithreading and networking. Unlike some similar Java-based projects, Turtle Tracks is a complete implementation of true Logo, supporting the same basic language syntax and semantics and most of the same primitives as other common Logo implementations such as Berkeley Logo. It also supports plug-in primitive sets and can be integrated with outside Java code as a scripting language.
