A Familiar Unknown, Samantha Sonnenfeld Aug 2023

A Familiar Unknown, Samantha Sonnenfeld

Theses

This thesis examines how using glass can challenge perceptions of small moments and their importance by overlaying stellar imagery on everyday spaces to imbue notions of investigative leisure with cosmic importance. I use many types of glass to reinterpret what function can mean and how objects can create lenses for understanding each other, our universe, and ultimately ourselves. Looking at where conversations are shared and introspection blossoms, I find that objects hold their own gravity and can draw us into a moment that sets the scene for solo or group development.
