It’s interesting how inspiration can be found in the simplest of things. Take for instance a pattern printed on a tissue box. I kept looking at it thinking what if it were simplified down to perfect circles and squares. Then that got me trying to figure out the exact geometric formulas. I researched terms for groups of circles (nested, tangent, coaxal, concentric, etc.), finding this Q&A quite interesting. And through several iterations I made these patterns in Adobe Illustrator.
