As a user of HeavyM VJ software and using nice shaders from the community, I was looking for a way to build a shader library in HeavyM
HeavyM supports standard ISF shaders and has some shaders to get started. And a tutorial.
I built an openFrameworks app to create gif files for preview the result. I just press the space bar 5 times to capture frames then the s key to save the gif file

void main(void) {
vec2 uv = 2 * (gl_FragCoord.xy / RENDERSIZE.xy - vec2(0.5));
float radius = length(uv);
float angle = atan(uv.y, uv.x);
float col = .0;col += 1.5*sin(TIME + 13.0 * angle + uv.y * 20);
col += cos(.9 * uv.x * angle * 60.0 + radius * 5.0 - TIME * 2.);
fragColor = (1.2 - radius) * vec4(vec3(col), 1.0);
