	Cinderella is a software package for interactive or dynamic geometry. Its first version was published in 1999 and was the first geometry software to be based on the theory of complex tracing3, thus avoiding mathematical inconsistencies and unmotivated discontinuities (modulo numerical errors). At the ICMS 2002 we will introduce the next major version of Cinderella and highlight its new features and new concepts.</p>

	Interactive Geometry is a major tool in modern geometry education and various software tools are available. We discuss the requirements of such tools and how they can be fulfilled. We also explain how a geometry tool can benefit from the Internet and present Cinderella{\textquoteright}s Caf{\'e}, which is an internet-aware geometry tool with a high mathematical background.</p>
