Goal: Arithmetic billiards are a geometric construction which allow an interesting visualisation for the greatest common divisor and the least common multiple of two positive integers. For an introduction to the subject, see this article. At least the following two generalizations can be addressed:
Collecting experimental data will allow to make conjectures concerning the shape of the path, which then one can try to prove. It is possible that the key ideas used for the base case can be extended to prove the conjectures.

Difficulty level: Bachelor thesis / EML 2,3
Tools: Any computer language suffices to describe the integer coordinates (however, a geometric visualisation could be very helpful).
