Some interesting links about curves:

• Geometry Formulas and Facts follow the links in Sections 7 and 8
• MacTutor follow the link to the "Famous Curves Index"
• Surf a graph and surface drawing programme
• Visualization of complex curves
• Laboratorio di Macchine Matematiche contains some wonderful animations of machines for drawing curves: simulazione in Italian
