dvcrn Sprite Animator
Generate animated pixel art sprites from any image. Uses nano-banana-pro (Gemini) to create a 16-frame sprite sheet in a single request, then assembles it into an animated GIF.
Quick Start
# Wave animation (default 16 frames)
uv run --with sprite-animator sprite-animator -i photo.png -o sprite.gif -a wave
# Bounce animation with larger sprites
uv run --with sprite-animator sprite-animator -i avatar.png -o bounce.gif -a bounce -s 256
# Keep the raw sprite sheet and individual frames
uv run --with sprite-animator sprite-animator -i pet.jpg -o dance.gif -a dance --keep-sheet --keep-frames

How It Works
- Creates a labeled 4x4 grid template (16 cells)
- Sends the template + source image to Gemini in ONE request
- AI fills each cell with a pixel art frame following the animation sequence
- Frames are extracted from the sheet and assembled into a looping GIF
Single-request generation ensures consistent style across all frames.
