Yes ... "Transparent swirls".
In the WV Swirl category. But it might be interesting to make a lot just with Transparent Swirls and see what people make of it.
Oh wait, I see your issue with #2. That could be a messed up cat eye.
So, yes, I'd pull #2 out and move it over to the cat eyes. And, yes, they're mostly "common". But I might try a lot with just plain transparent swirls on the theory that "what do you have to lose".
