Briefly describe your project key features and tech stack used.
A button allows you to switch between day and night mode. In day mode a dark background and stars are added which makes it easier to see the lights. Everytime you start the app a new pattern of lights is generated. The light meshes are created by tracing a point in a vector field on a surface of a sphere. A fragment shader is then used to create the shimmering effect. The stars are created using a particle system and a fragment shader is used to make them twinkle. The tech stack consists of 8th Wall, Three.js and GLSL.

What was the inspiration for your project? (Optional)
I wanted to replicate a natural phenonenum that occurs in the sky and the Northern Lights seemed like a particularly visually interesting phenonenum to recreate.
