No, I haven't seen it. However, this last summer, I purchased a hula-hoop from Walmart's summer section, just one of those light ones w/beads in it that make noise. I had never hula hooped before and picked it up very quickly. It is fantastic especially when the weather isn't nice enough for a walk/jog. There is a Spark's Team Page dedicated to hooping, check it out for some possible information. Good luck, it takes a little practice, but is great!
