Spicy only exists in an alpha version, and has not been updated since 2002!!!
The interactive constructive geometry software SPICY is now available
And it's free! Just download and use it!
The tutorial section is not finished yet, but I hope that the user interface is easy to understand, so that you won't need explanations in most cases.
For a description of SPICY's main features and some screen shots, check out the overview section. The tutorial contains an easy-to-understand step-by-step introduction to SPICY.
This site (and the software SPICY itself) is under development, so that some pages do not have any content yet - sorry for this inconvenience.
