31⍝ Conway's game of life

33⍝ This example was inspired by the impressive demo at
34⍝ http://www.youtube.com/watch?v=a9xAKttWgP4
35
36⍝ Create a matrix:
37⍝ 0 1 1
38⍝ 1 1 0
39⍝ 0 1 0
40creature ← (3 3 ⍴ ⍳ 9) ∈ 1 2 3 4 7 ⍝ Original creature from demo
41creature ← (3 3 ⍴ ⍳ 9) ∈ 1 3 6 7 8 ⍝ Glider
42
43⍝ Place the creature on a larger board, near the centre
44board ← ¯1 ⊖ ¯2 ⌽ 5 7 ↑ creature
45
46⍝ A function to move from one generation to the next
47life ← {∨/ 1 ⍵ ∧ 3 4 = ⊂+/ +⌿ 1 0 ¯1 ∘.⊖ 1 0 ¯1 ⌽¨ ⊂⍵}
48
49⍝ Compute n-th generation and format it as a
50⍝ character matrix
51gen ← {' #'[(life ⍣ ⍵) board]}
52
53⍝ Show first three generations
54(gen 1) (gen 2) (gen 3)

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