I don't know... I think there have been a lot of advances in Wacky Wall Walker technology. The early Wall Walkers, even before my time, were nothing more than balls of tape. Sorta sticky, but hardly wacky. When I was a kid (and remember, I'm a lot older than you) the Wall Walker technology had advanced quite a bit, but I don't think the "ever-goo" was introduced on the scene until the mid 90's.
