Hi dryriver,

I'm not sure if this is exactly the same effect that you're looking for,
but Array Dir can produce some interesting patterns very quickly.

In this example the original pair of 6 sided curves was arrayed 5X then the result was
arrayed 5X and then that result was arrayed 5X. If you gave it some thought you could
probably create some patterns that aren't the same as what you'd get from a Grid array
because you can array at an angle rather than just along the XYZ axes
And if you combined Array Dir with Array along a curve and Circular Array, the possibilities are endless!
