Concentric circles, but not quite.

Does anyone know how to easily reproduce an expanding pattern made of circles like this: http://i1.creativecow.net/u/181152/screenshot2011-09-01at6.35.16pm.png

 

Many thanks.

 

Richard.

    Here's one easy method....

    The key aspects are the Stroke settings at the bottom. Your stroke weight and gap length may need to change to suit your needs.

    Richard,

     

    To avoid confusion, the term dots is used for the small filled circles here.

     

    The distance between dots seems to be about the same as their size. This corresponds to 6 dots times the number of the circle (6 dots in the first circle round the central dot etc).

     

    A  way that is more accurate than using the Polar grid is a Blend based on a single outer circle. The exact size and number of Blend steps depend on the desired number of circles/dots. For 61 circles round a central dot (with 366 dots in the outermost circle), you may:

     

    1) Create a circle with Width = Height = 233 times the size of the dot, give it a Stroke Weight = the dot size, set the Cap to Round, tick Dashed Line with Dash = 0 and Gap = twice the dot size;

    2) Ctrl/Cmd+C+F to create a copy and set W = H = 0;

    3) Object>Blend>Options set Specified Steps = 60 (I always prefer to set Orientation to Align to Path unless specifically not, silly sometimes);

    4) Select the two circles and Object>Blend>Make;

    5) Enjoy.

     

    If you have too many circles/dots, you may:

     

    6) Object>Blend>Expand and delete the unnecessary ones from the outside in.

     

    You may change the dot colour at any time.

     

    It may be mentioned that the size of the outer circle is adjusted for the inherent inaccuracy of the circle shape.

    That's a beautiful way, Jacob.

     

    Here's your suggestion as an image:

    Thank you, Peter. Actually, with the e word you gave me an important key to a very difficult word in a (completely unrelated) rhyme translation for a friend, from a language I know far too little about (I do not even know the original word, only a few non rhyming English words with approximate meanings); I had almost given up, but now I am back in the thesaurus.

    And thank you, Scott. The n word actually pointed at another rhyming option. I begin to fear that I shall end up with too many.

    Another e word to rhyme with the former:

    The Elephant

     

    When people call this beast to mind,

    They wonder more and more

    At such a LITTLE tail behind,

    So LARGE a trunk before.

    (Belloc)

    Very nice, Steve. I used the elephant match to come up with synonyms that matched the original unknown word and rhymed on yet another word.

    For my part you are welcome, Richard.

     

    Is there a reason to delete the central dot?
