| ⍝ Conway's game of life | |
| ⍝ This example was inspired by the impressive demo at | |
| ⍝ http://www.youtube.com/watch?v=a9xAKttWgP4 | |
| ⍝ Create a matrix: | |

| ⍝ 1 1 0 | |

| creature ← (3 3 ⍴ ⍳ 9) ∈ 1 3 6 7 8 ⍝ Glider | |
| ⍝ Place the creature on a larger board, near the centre | |
| board ← ¯1 ⊖ ¯2 ⌽ 5 7 ↑ creature | |
| ⍝ A function to move from one generation to the next | |
| life ← {∨/ 1 ⍵ ∧ 3 4 = ⊂+/ +⌿ 1 0 ¯1 ∘.⊖ 1 0 ¯1 ⌽¨ ⊂⍵} | |
| ⍝ Compute n-th generation and format it as a | |
| ⍝ character matrix | |

| ⍝ Show first three generations | |
| (gen 1) (gen 2) (gen 3) | |

| <p>Simple mode that tries to handle APL as well as it can.</p> | |
| <p>It attempts to label functions/operators based upon | |
| monadic/dyadic usage (but this is far from fully fleshed out). | |
| This means there are meaningful classnames so hover states can | |
| have popups etc.</p> | |
