Go to Google, click on graphics, put lemniscate in the search box and take a peek at lots of kinds of leminscates, a few of which could be accomplished, large scale in the sand, riding a bike. :)

Bekah intended to say "click on images", I think. Anyway there are lots, as she says. For the bicycle, look at Bike Rodeos, Bicycle Confidence Course, Change of Balance, when you get to the site she gives above.

Again, I asked too soon. The Google images led me to www.ipfw.edu/math/Coffman/ pov/booth7.jpg
where I found the definition of the lemniscate of Booth, about which I had asked.
