Conveying Movement.

I've been pondering over the different ways in which one can give the impression of movement within an art quilt.  There are many of course, usually involving repetition, rhythmic elements, and/or gradation of any aspect of any element.
 Look at the repetition both of the vertical elements and the diagonal elements in this piece:

Five Mills Rampant

Can't you just see the old machines chugging up and down, the crank shafts moving?


 In cartoons, the artist uses lines: skinny curved lines around the object that is moving - havn't ever seen that done in a quilt!  but I'm sure it would work.

Also, notice that a usually vertical object is horizontal - i.e. his ears.  We often see this on pictures of  flags:

You can almost feel the wind that has this flag  furling out across the deep blue sky.....

And while I've not made a quilt with a flag - you can see the same effect with smoke in this quilt: Oh, What Pretty Smoke!

 And in Heavy Metal,  I used undulating silver quilting lines in the water to give the impression of the constant movement of water on a large lake:

In a more recent piece about dancers...I split the images so that the viewer's eye must travel across the piece to complete the image:

Do write and let me know your favorite techniques for showing movement - and also comment on which of the above you think is the most effective...your first impressions are very important!

And, if you have been, thanks for reading!
