Pseudo languages are usually subsets of existing programming languages, and thus can be used to teach all the basic programming concepts. This however leads to a fact that programs written in pseudo code are usually not executable as-is. With this in mind we have developed a program visualization tool called ViLLE. The tool has a built-in pseudo language, a subset of Python. User can add programming examples written in Java and translate them to other languages. Additionally, a user can define own pseudo languages and modify the existing syntaxes.
