Catch that speeding turtle: latching onto fun graphics in CS1

Graphics are a great way to keep students motivated early in a computer science program. This paper introduces a simple Ada graphics package that simultaneously meets two goals: it provides a easy to understand graphics package that leads to enjoyable projects in CS1, and it is an appropriate tool for teaching fundamental computer science concepts to beginning programmers. The package is an Ada implementation and extension of a Java TutleGraphics package used at a number of universities.
