XWizard

XWizard is a free (web) tool for the automatic visualization, manipulation and PDF generation of many types of objects from theoretical computer science (such as Turing machines, push-down and finite automata, Chomsky grammars etc.). A broad range of algorithms can be applied to the objects, producing intuitive and customizable views. XWizard is well-suited for students’ self-studies, and it is powerfull in aiding teachers at the creation of course material such as exercises (the X in XWizard stands for “eXercise” – and also for “anything”).
