Turtle Graphics is a Home & Education software developed by Brett Geren. After our trial and test, the software is proved to be official, secure and free. Here is the official description for Turtle Graphics:

BSEditor: Turtle Graphics is an educational program geared for children. The idea is based off the Logo Programming Language and Turtle Graphics vector programming methods. The project involves a GUI to see the turtle, all commands, a console, and a program editor. Turtle Graphics is released under the new OpenBSD license.
