John Sullivan and I were greatly impressed by Juergen Richter-Gebert's demonstration of his "Cinderella" interactive geometry software at VismathII in Berlin last summer. Later that summer I visited Juergen in Munich and came away even more impressed, together with an examination copy of his most recent "upgrade". The package could be useful in many of our undergraduate and even some graduate geometry courses. It's engine runs entirely in the complex field and it deals with appropriate problems in terms of the Riemann surface of its equations.

We invite you to come by the grafiXlab for a private demonstration.
