A high-level programming language noted for its ease of use and
graphics capabilities. It is a recursive language that contains
many list processing functions that are in LISP, although Logo's
syntax is more understandable for novices. Stemming from a
National Science Foundation project, Logo was created by Seymour
Papert in the mid-1960s along with colleagues at MIT and members
of Bolt Beranek & Newman. Originally developed on large
computers, it was later adapted to many personal computers. A

Turtle Graphics is the graphics language built into Logo, which
allows complex graphics images to be created with a minimum of
coding. The turtle is a triangular-shaped cursor, which is moved

driving it, for example, go forward 100 units, turn right 45
degrees, turn left 20 degrees. The following
