FMSLogo supports multiple turtles, and 3D Graphics. FMSLogo allows input from COM ports and LPT ports. FMSLogo also supports a windows interface thus I/O is available through this GUI- and keyboard and mouse events can trigger interrupts. Simple GIF animations may also be produced with the GIFSAVE command. Jim Muller wrote The Great Logo Adventure, a complete Logo manual using MSWLogo as the demonstration language.
FMSLogo evolved from MSWLogo: An Educational Programming Environment, a free, open source implementation of the Logo programming language for Microsoft Windows. It is released under the GPL and is mainly developed and maintained by David Costanzo.
