Resultant of 2 SHM's at right angles

[Geocentric]

When 2 simple harmonic motions are applied to a particle at right angles to each other having time periods in the ratio 1:2, you get a figure of eight. When the phase difference is (pi)/4,3(pi)/4,... you don't get a perfect figure of eight.Can it be called a distorted eight or is there any other name? I would like to follow the nomenclature that is universally accepted.That is why I asking.Thanx in advance.

There was a name for these figures... what did you call them? Lassigne's diagram? Lajous? L-something, I think... What was that exactly?

And see what I found in the search! Cool java app.
