Random opacity, size and position of circles to move

[Gumbo]

Hi,

 

I have to create a 300x250 banner that will have circles moving slowly around the banner, changing size and position all randomly. Also they will need to be at random opacities. See the image attached. The opacity doesn't necessarily need to change. They all need to stay within 100px from the top and 20px from the bottom. Can be svg shapes or png images like the attached. I don't know where best to even start! Can anyone help?

 

Thanks for any help.

Hi @Gumbo

 

This sounds a lot like this thread:

I think that info should get you started. Happy tweening.
