Zoran Putnik




In this paper we will show an implementation of turtle graphics features in functional programming language LISP, version LispKit Lisp, implemented at the Institute of Mathematics in Novi Sad [1, 2]. Great value of using graphics, specially turtle graphics, abilities in education - programming languages, functional programming, recursion and program modularity will be presented. Some elementary details about turtle graphics and it's implementation will be explained for better understanding of its power in process of education.
