There is tremendous value in reflecting back on God and His (Triune) nature through creation. Bonaventure, a medieval theologian I have come to greatly appreciate for his thoughts on the Trinity, would talk about "exemplarity" and within his system this exemplarity was the the middle term emphasizing the Son within the triad of emanation (F), exemplarity (S), and consummation (HS). Bowman, in The Cosmic Exemplarism of Bonaventure, writes, "Exemplarism can be defined as the doctrine of the relations of expression between God and creatures. It presupposes that God is the prototype of all that exists and he expresses himself in creatures, so that as a result creates express the Creator."

In the sermon I mention both structure (S) and beauty (HS) and how they are seen in the peacock's tail. Stuart Burgess, a Christian and engineer, has written a journal article on the peacock's tail, but his brief talk here on Youtube is far more accessible and absolutely delightful. In fact, I encourage you to show it to your children. I trust that as you remark on the unbelievable design, structure, and beauty of the peacock's tail, your heart will be caught up to praise our Triune Creator.
