turtleSpaces is an advanced Logo programming language interpreter that facilitates easy creation of three-dimensional artworks, animations and games. It is based on and compatible with Apple Logo II (LCSI Logo II), which gives it a cool retro feel, but with a vastly improved user interface and modern capabilities such as multiple threads and turtles.

About Logo

Created in the 1960s to be a computing language understandable to children, Logo (not an acronym, but from the Greek word Logos, meaning ‘speech’) was initially designed as a language for manipulating… well, language, taking list processing concepts from LISP and containing a number of functions (called primitives) that allowed for the manipulation of these lists.

The turtle came later in an attempt to add geometry to Logo’s proposed curriculum, first a physical turtle, then as computer displays became more common a ‘virtual’ one, which drew lines on the screen.

Logo became very popular in the 1980s, as versions of the language appeared for a variety of home computers, including the Apple II, Atari and Commodore 64. But these versions were limited by the computers they were on, and slow.

turtleSpaces is an implementation of the Apple II version, but on modern hardware, and it is much less limited! But it is Logo in spirit, as it was in the 1980s, just much more useful and accessible, with the addition of dozens of shape primitives, tables, databases, search functionality, list manipulation, positional and vector functions, cameras, lights, music hatchlings and much, much more.

There are dozens of examples that show off these various capabilities, including partially-developed games.

Further, it runs in web browsers (WebAssembly), and has applications for Windows 10, MacOS X and Linux. So there are plenty of ways to enjoy turtleSpaces!
