+    dollcode is a trinary number, with a ▖, ▘, ▌ denoting the three bit states,
+    with most significant bit on the left side.
+  </p>
+  <p>
+    if we were to count from 1 to 16, we would get ▖ ▘ ▌ ▖▖ ▖▘ ▖▌ ▘▖ ▘▘ ▘▌ ▌▖ ▌▘
+    ▌▌ ▖▖▖ ▖▖▘ ▖▖▌ ▖▘▖
+  </p>
+  <p>
+    this is a simple case of looping through the number, and checking each
+    modulus 3 section, and replacing it with one of the 3 characters.<br /><b
+      >see source for the algo, it's simple.</b
