bodyless forms

My form so far has been mostly consisting of two parts - the lines on the outside, and the body of ellipses in the middle. This is what has been making it appear like a creature of sorts.

So i decided to go back to what I had been trying earlier, and do some more experiments of the form without the ellipses to see what it would look like.

I guess i was trying to return back to my initial concept based on the northern lights.

However I found these to not be as interesting visually as the forms with a 'body'. I prefer the relationship between the ellipses moving directly along the path, in contrast to the lines which are moving dynamically up and down.

Here are a few trials anyway:
