Maybe the turtle could be of interest? ------------------------------------------------------------- Lab: Turtle Geometry - JTurtle User Guide Author: L. Fraser Jackson I am indebted to Brian M. Schott for many helpful comments. He has a different Turtle graphics system which has a range of 3D tools and multiple turtles. It can be downloaded from the JWiki. See http://www.jsoftware.com/jwiki/FrontPage
To advance the lab, select menu Studio|Advance or the corresponding shortcut. -- Chapter 1 Introduction ----------------------------------- -- ((1) 1 of 40) Is this for you? --------------------------- This lab is an introduction to JTurtle for J users with some experience of J at the J Primer level. Even beginners should be able to learn enough to use Turtle Geometry and combine it with other elementary geometric ideas by working through the Lab. Experienced programmers may prefer to use the help window accessed by help'' after load 'turtle'. It should be useful to others after running this Lab. ) 2009/8/22 Andrew Nikitin <[email protected]>: > > Hi, > > One of my children showed some interest in programming. > So I am trying to find a base of programming problems from very simple and > going up in complexity.
