Would it be easier to see any drift if the phase was set to make a line rather than a circle? A small shift in a circle just makes a not-round circle. A small shift on a line makes a slight opening. Or is the drift so huge that this question isn't interesting. (just wait a bit and the picture will change) -- These are my opinions, not necessarily my employer's.
