The new resulting pattern is played over the time period of the original pattern:

Only `when` the given test function returns `True` the given pattern
transformation is applied. The test function will be called with the
current cycle as a number.

The above will only apply `striate 4` to the pattern if the current
cycle number contains the number 4. So the fourth cycle will be
striated and the fourteenth and so on. Expect lots of striates after
cycle number 399.
