You will need to use one (or several) custom shaders to do this by using the ShaderMaterial class.
@HiteshSahu has ported a shader toy here if you want to see how he has done it: Examples from the playground
You also have a number of other ones from @Pryme8 here: Shader Talk - Conversations on GLSL
