I didn't quite follow the original construction --
where is the Hoola-Hoop (tm) ??... I'd agree with John that, if
you're holding the hoop centered on your head, it's just a circle, as
the visual field is essentially euclidean (there was a nice book
on noneucldidean geometry that mentioned an experiment on this, but
it seemed to get the wrong (opposite) conclusion.... or,
were you making an observation like that, that
any circle in perspective is an ellipse?
