flux background here
now make a main menu 
@chocopiexd good!

uniform float iTime; uniform vec2 iMouse; uniform vec2 iResolution; void main(void){ vec2 uv = 1.0 + 2.0*gl_FragCoord.xy / iResolution.xy; uv.x *= iResolution.x / iResolution.y; vec2 ms = (iMouse.xy / iResolution.xy); // background vec3 color = vec3(0.9 + 0.1*uv.y); // bubbles for( int i=0; i<40; i++ ) { // bubble seeds float pha = sin(float(i)*546.13+1.0)*0.5 + 0.5; float siz = pow( sin(float(i)*651.74+5.0)*0.5 + 0.5, 4.0 ); float pox = sin(float(i)*321.55+4.1) * iResolution.x / iResolution.y; // buble size, position and color float rad = 0.2 + 0.5*siz; vec2 pos = vec2( pox, 1.0rad + (2.0+2.0*rad)*mod(pha+0.1*iTime*(0.1+0.1*siz),1.0)); float distToMs = length(pos  ms); pos *= length(pos  (ms * 1.50.5)); float dis = length( uv  pos ); vec3 col = mix( vec3(0.1,0.2,0.8), vec3(0.1,0.4,0.8), 0.5+0.5*sin(float(i)*1.2+1.9)); // col+= 8.0*smoothstep( rad*0.95, rad, dis ); // render float f = length(uvpos)/rad; f = sqrt(clamp(1.0f*f,0.0,1.0)); color = col.zyx *(1.0smoothstep( rad*0.95, rad, dis )) * f; } // vigneting color *= sqrt(1.50.5*length(uv)); gl_FragColor = vec4(color,1.0); }
