How to Code: Galactic Light Trails

Learn how to create mesmerizing galactic light trails using HTML5 Canvas and JavaScript in this 38-minute tutorial. Discover techniques for rotating the entire canvas, manipulating opacity fills, and introducing object randomness to achieve an eye-catching time-warp effect in space. Start with initial canvas setup, then progress through creating randomized particles, implementing canvas rotation for a spin effect, and adding glow effects. Explore methods to spawn particles off-canvas, randomize colors, and create dynamic light trails on mouse interaction. By the end, gain the skills to produce stunning visual effects that simulate interstellar travel.
