-My first procedurally generated animation drawing concentric heart
-growing from the center of the screen. The source code for the
-program used to create this piece is [available on my GitHub](https://github.com/lavafroth/drawhearts).
+My first procedurally generated animation using shaders.
+
+The shader can be visualized with `glslViewer`.
+
+```glsl
+uniform vec2 u_mouse;
+uniform vec2 u_resolution;
+uniform float u_time;
+
+void main (void) {
+    vec2 st = gl_FragCoord.xy/u_resolution.xy;
+   float aspect = u_resolution.x/u_resolution.y;
+    st.x *= aspect;
+
+    // positioning shenanigans
+    st.x = st.x * 2.0 - 1.8;
+    st.y = st.y * 2.0 - 0.9;
+
+    float r = st.x*st.x + st.y*st.y - abs(st.x)*st.y;
+    r *= 2.0;
+
+    float duration = 3.0;
+    float bin = 0.1;
+    float scaled_time = fract(u_time/duration);
+    float loop = scaled_time * 2.0 - 1.0;
+    float r_disc = floor((r + loop*loop)/bin) * bin;
+
+    vec3 deep_pink = vec3(0.917, 0.235, 0.478);
+    vec3 light_pink = vec3(0.976, 0.780, 0.803);
+
+    if (r_disc >= 1.0) {
+        gl_FragColor = vec4(deep_pink, 1.0);
+        return;
+    }
+    vec3 color = mix(deep_pink, light_pink, r_disc);
+    gl_FragColor = vec4(color,1.0);
+}
+```
 
 I tinkered around for quite a while before discovering that I can intersect two $xy$ skewed ellipses
 with the absolute value operator. Here's my custom equation for the heart shape.
