From the project website (accessed 2012-02-21):
This project aims to provide an online tool for those trying to get to grips with Greek verbal morphology. In its current state, it offers two modes. First, it can simply present the user with a single verb form either in Greek to recognise or described in English to recall before then displaying the answer. Second, the student can enter 'challenge mode', where he or she can earn points recognising forms.
In the future, I hope to make use of the Perseus source code to generate challenges based on specific works, e.g. 'Can you identify the verbs used in Plato's Republic?', etc.
Anyone interested, particularly if they have expertise in java, is very welcome to help out. You can contact me through the tool's feedback form.
