Rangoli Patterns

Traditional Indian Rangoli patterns overlaid on a changing colour background made by a fragment shader running on your GPU, written in GLSL and using trigonometric functions to create shapes that mutate with time.

Tools used:

• GIMP to bucket-fill regions with black
• Imagemagick to make white areas transparent
• GLSL to code the fragment shader
• the Javascript WebGL API to control shaders in the browser
