Abstract
An operad structure on certain bicolored noncrossing configurations in regular polygons is studied. Motivated by this study, a general functorial construction of enveloping operad, with input a colored operad and output an operad, is presented. The operad of noncrossing configurations is shown to be the enveloping operad of a colored operad of bubbles. Several suboperads are also investigated and described by generators and relations.
