I’m actually indifferent to them, but, rather than choosing “other,” I picked “dislike” as that’s where my feelings edge on them. They look a bit, I dunno, kitsch to me.
I am indifferent to them, so I guess that puts me in the “other” category.
Well, they are. That’s part of the appeal. 
I believe the term “groovy” encapsulates their kitsch character and appeal as well as the pleasant unpredictable shifts of shapes and colors.
I’m surprised they haven’t changed much with time. You could have them in several layers, stories, blob colors.
