My sister-in-law and her mother both collect frog-related items (the latter by choice, the former because her mother decided she should), so I’ve made the occasional frog-themed art egg. 

The egg below is a large goose egg I wrote in 2009 for Laurie’s birthday.  It is a simple design; the frog motif was taken from the scrub jacket of a co-worker, while the water lilies and dragonflies were my own additions.
