This is a math inspired drawing.
It's the equation of a circle!

I enjoy creating math inspired designs with formulas or equations
with a goal of making math more interesting & visually appealing.

I created this drawing on Glossy, HP Presentation paper
& used black ink 0.7 fine point, Uni-ball Vision pen.

I draw black & white, pen & ink designs,
creating illusions of movement,
using basic recognizable shapes,
lines, patterns, and figments of imagination.

All my designs are drawn freehand.
