🌌 Python Turtle The Neon Wave Tunnel

 

Code:

import turtle import math import time screen = turtle.Screen() screen.setup(700, 700) screen.bgcolor("#020208") t = turtle.Turtle() t.hideturtle() t.speed(0) t.width(2) colors = [ "#00ffff", "#7c4dff", "#ff2d75", "#00ff9d", "#ffe600" ] for layer in range(35): t.color(colors[layer % len(colors)]) t.penup() for i in range(180): x = -260 + i * 3 wave = math.sin(i * 0.09 + layer * 0.35) * (35 + layer) y = wave + layer * 2 if i == 0: t.goto(x, y) t.pendown() else: t.goto(x, y) screen.update() time.sleep(0.003) time.sleep(0.08) # ✨ Center glow for r in range(30, 2, -3): t.penup() t.goto(0, -r) t.dot(r, colors[r % len(colors)]) screen.update() time.sleep(0.06) turtle.done()

Explanation:

1. Import Libraries

import turtle

import math

import time

turtle → Creates the drawing.

math → Calculates the wave pattern.

time → Controls animation speed.

2. Create the Screen

screen = turtle.Screen()

screen.setup(700, 700)

screen.bgcolor("#020208")

Creates a 700 × 700 canvas.

Sets a dark background.

3. Configure the Turtle

t = turtle.Turtle()

t.hideturtle()

t.speed(0)

t.width(2)

Creates the turtle.

Hides the turtle cursor.

Sets maximum speed.

Sets line thickness to 2.

4. Define Neon Colors

colors = [

    "#00ffff", "#7c4dff",

    "#ff2d75", "#00ff9d",

    "#ffe600"

]

Stores five neon colors.

These colors are used for different wave layers.

5. Create Multiple Wave Layers

for layer in range(35):

Creates 35 separate wave layers.

Each layer forms part of the tunnel effect.

6. Select the Layer Color

t.color(colors[layer % len(colors)])

Cycles through the neon colors.

layer % len(colors) prevents the index from going out of range.

7. Prepare for Drawing

t.penup()

Lifts the pen before moving to the starting point.

8. Generate Wave Points

for i in range(180):

Creates 180 points for every wave.

9. Calculate X Position

x = -260 + i * 3

Starts at -260.

Moves 3 pixels to the right each time.

10. Calculate the Wave

wave = math.sin(i * 0.09 + layer * 0.35) * (35 + layer)

Uses sin() to create a smooth wave.

layer * 0.35 shifts each layer.

(35 + layer) gradually increases the wave size.

11. Calculate Y Position

y = wave + layer * 2

Combines the wave movement with the layer offset.

Moves each layer slightly upward.

12. Start the Wave

if i == 0:

    t.goto(x, y)

    t.pendown()

Moves to the first point without drawing.

Then starts drawing the wave.

13. Continue the Wave

else:

    t.goto(x, y)

Connects each calculated point.

Creates the continuous wave line.

14. Animate the Wave

screen.update()

time.sleep(0.003)

Updates the screen.

Adds a tiny delay for smooth animation.

15. Pause Between Layers

time.sleep(0.08)

Adds a short pause after each wave layer.

Makes the tunnel formation visible.

16. Create the Center Glow

for r in range(30, 2, -3):

Creates several shrinking circles.

The radius decreases from 30 to 3.

17. Draw the Glow

t.penup()

t.goto(0, -r)

t.dot(r, colors[r % len(colors)])

Moves to the center.

Draws colorful dots of decreasing size.

Creates a glowing-center effect.

18. Animate the Glow

screen.update()

time.sleep(0.06)

Updates the screen.

Adds a small delay between glow layers.

19. Finish

turtle.done()

Keeps the Turtle window open.

Ends the animation.
