Turtle Spirograph (Random-Color Circles)

A tiny Python program that uses the built-in turtle module to draw a spirograph-style pattern: 100 circles of radius 100, each rotated by 10°, with a new random RGB color every turn.

✨ What It Does

• Draws concentric/overlapping circles, producing a spirograph effect.
• Picks a new random RGB color for each circle.
• Uses the fastest turtle speed for quick rendering.
• Keeps the window open until you click.

🧩 How It Works (High-Level)

1. Set up a Turtle named tim, enable 0–255 RGB mode with turtle.colormode(255), and set speed to "fastest".

2. Define random_color() to return a random (r, g, b) tuple.

3. Loop 100 times:

   • Change the pen color to a new random color.
   • Draw a circle of radius 100.
   • Rotate the turtle’s heading by 10 degrees (setheading(heading + 10)).

4. Wait for a mouse click to close the window.

✅ Requirements

• Python 3.8+ (any recent Python 3 works)
• No external dependencies (uses the standard library)

▶️ Run It

Save the script as spirograph.py, then run:

python spirograph.py

On some systems you may need:

python3 spirograph.py

Click the window to exit when you’re done admiring the art.

🔧 Customize

Tweak these values to change the look:

• Number of circles Increase or decrease the loop count:

  for _ in range(120):  # was 100

• Circle size (radius)

  tim.circle(80)  # was 100

• Rotation step (degrees per circle) Smaller steps create denser patterns; larger steps are more star-like:

  tim.setheading(tim.heading() + 5)   # denser
  tim.setheading(tim.heading() + 15)  # sparser

• Speed "fastest" is ideal, but you can slow it down to watch the drawing:

  tim.speed(10)  # 1 (slow) to 10, or "fastest"

• Color strategy Replace random_color() with a palette or gradient for themed visuals.

🐛 Troubleshooting

• Blank/hidden window: Some IDEs buffer the turtle window behind others—look for a new window or run from a terminal.
• Slow rendering: Keep "fastest", reduce the loop count, or increase the rotation step.
• Colors look muted: Ensure turtle.colormode(255) is called before setting RGB colors.
