I built a web tool that transforms PDB protein structures into retro-style pixel art icons.

Features: - Search by PDB ID or upload .pdb/.cif files - 25+ color palettes (viridis, plasma, rainbow, etc.) - 4 display styles (cartoon, stick, sphere, surface) - Export as PNG or animated GIF - All generated images are CC0 (public domain)

Built with Next.js, 3Dmol.js, and custom pixelation/outline shaders.
