Then run!
void mainImage( out vec4 fragColor, in vec2 fragCoord )
{
vec2 p = (fragCoord.xy * 2.0 - iResolution.xy) / iResolution.y * 0.5 - 0.5;
vec3 C = vec3(0.0);
for (float i = 1.0; i < 99.0; i++)
{
float j = i + 1.0;
vec2 q = p - vec2(sin(j + 1.0), sin(j + iTime)) / (sin(iTime - j / 8.0 + 9.0) + 1.0) * 0.1;
C += 0.01 / length(q * 99.0);
}
fragColor = vec4(C * 5.0, 0.0);
}
