【Shadertoy】Crystal Tunnel - The crystal grows, forms veins, then shatters.

Summary

• Inspired by "Cellular Tiled Tunnel," I wanted to create one with more transient animation and clear colors.
• So, I decided to generate a tunnel by growing crystals and then shuttering at the end.
• The crystal looks like a transparent object but is artificially simulated by adding colorful point lights and then tone mapping with gamma correction.
