| rlm@0 | 3 library in Clojure. This namespace samples images |
| rlm@0 | 4 and creates a Grid object containg many small circles |
| rlm@0 | 5 of different colors, one for each sampled pixel |

| rlm@0 | 7 I'm submitting this late just to show offwhat I was |
| rlm@0 | 8 working on --- I don't expect it to be graded. |

| rlm@0 | 10 LATE-Heart-Blending.jpg is the source, |
| rlm@0 | 11 Late-heart-output is the sampled output." |
