Designer
A designer is a person who designs. More formally, a designer is an agent that "specifies the structural properties of a design object". In practice, anyone who creates tangible or intangible objects, products, processes, laws, games, graphics, services, and experiences is referred to as a designer.

But it is not only of space in the Church which we ought to be jealous, but also of the interior of the house of God in us, so that it might not become a house of merchandise, or a den of robbers.
Ambrose, Commentary on John 2:16, Exposition of the Psalms of David 118 (PL 15 1457B)
Interior
The trick is to maintain a kind of naïve amazement at each instant of experience—but, as Montaigne learned, one of the best techniques for doing this is to write about everything. Simply describing an object on your table, or the view from your window, opens your eyes to how marvelous such ordinary things are. To look inside yourself is to open up an even more fantastical realm.
Sarah Bakewell, How to Live (2010), p. 37
