Project 01
Praewa Pitiphat

Below is the shadertoy code. For project 01, I used the provided code "Voronoi_w_circles" and made some modifications. I created 2 circles. One is a user-controlled circle where the user can control it by using mouse. The other circle is a still circle. When the two circles intersect each other, the intersected area will turn into a noisy colored section (also, the ring pattern will show up as well!).
