What the `at` function does is sequence events at particular time ticks
modulus the second argument.

So here we are saying take the current tick % and wrap it around at 8:

0 1 2 3 4 5 6 7 0 1 2 3 4 5 6 7 0 1 ....

Then the map says "when you hit 2 return 60, and when you hit 7 return 55".

So that's why we get the pattern:

0 1 2 3 4 5 6 7 0 1...
nil nil 60 nil nil nil nil 55 nil nil...

The 60 is appearing at 2 and the 55 is appearing at 7 and so on.

Cheers,

Chris.
