algorithmic-art

name	algorithmic-art
description	Create generative / algorithmic art and visual patterns with code — fractals, geometric tilings, flow fields, color gradients, parametric shapes — rendered to an image. Use when users want procedurally generated art, a cool pattern, a wallpaper, or 'make something with code'. Triggers on mentions of generative art, algorithmic art, fractal, pattern, procedural, flow field, wallpaper, 生成艺术, 算法艺术, 分形, 图案, 壁纸.
license	Proprietary. LICENSE.txt has complete terms
compatibility	Requires python3 with Pillow (PIL) for raster output, or stdlib for SVG. Works on macOS, Linux, and Windows.

Algorithmic Art

Make art from rules. Render to a file under tmp/, then send it with send_message. For raster, check python3 -c "import PIL"; if Pillow is missing, generate SVG with the stdlib (no deps).

SVG (no dependencies) — generative grid

python3 - <<'PY'
import random, math
W=H=600; cells=20; s=W//cells
parts=[f'<svg xmlns="http://www.w3.org/2000/svg" width="{W}" height="{H}">',
       f'<rect width="{W}" height="{H}" fill="#0b1021"/>']
for i in range(cells):
    for j in range(cells):
        hue=(i*j*7)%360
        r=random.uniform(3, s/2)
        parts.append(f'<circle cx="{i*s+s//2}" cy="{j*s+s//2}" r="{r:.1f}" '
                     f'fill="hsl({hue},70%,60%)" opacity="0.8"/>')
parts.append('</svg>')
open("tmp/art.svg","w").write("\n".join(parts))
print("wrote tmp/art.svg")
PY

Raster with Pillow — fractal (Mandelbrot)

python3 - <<'PY'
from PIL import Image
W=H=700; img=Image.new("RGB",(W,H))
px=img.load()
for x in range(W):
    for y in range(H):
        c=complex(-2.2+3.0*x/W, -1.5+3.0*y/H); z=0; i=0
        while abs(z)<=2 and i<60: z=z*z+c; i+=1
        px[x,y]=(i*4%256, i*7%256, i*11%256)
img.save("tmp/mandelbrot.png")
print("wrote tmp/mandelbrot.png")

Ideas to vary

• Fractals (Mandelbrot/Julia), flow fields (Perlin-ish noise on a vector grid), recursive trees, circle/Truchet tilings, color-gradient meshes, parametric curves (Lissajous).
• Expose a few parameters (palette, density, seed) and iterate with the user.

Guidance

• Save under tmp/ and deliver via send_message with attachment_path.
• SVG scales crisply and needs no deps — prefer it for geometric work; use Pillow for per-pixel.
• Keep render sizes reasonable (≤ ~1000px) so it's fast; offer to upscale if they like it.
• For prompt-driven realistic images (not code-based art), use the generate_image tool instead.
