MOSS is a pixel editor that treats every brush as a programmable tool. Unlike traditional painting software, each brush can blend, spread, drip, grow, or glitch in unique ways. Every cell on the canvas holds data that brushes can manipulate, creating emergent patterns and unexpected results that artists can refine into finished pieces.

The platform includes 50+ brushes covering everything from basic paint and ink to experimental effects like vine growth, wet drips, and generative plaid patterns. What sets MOSS apart is its complete programmability - artists can modify how brushes spread, what they leave behind, and how they respond to colors. This customization transforms the software from a simple painting tool into a creative coding environment.

MOSS encourages exploration through happy accidents, where unexpected brush behaviors lead to favorite discoveries. The sharing feature allows artists to save their work and send it to friends, who can then open the same image and experiment with identical brushes and palettes. This creates a collaborative ecosystem where creative techniques can be easily passed between users.
