Ok,… another something I want to work out. If you scroll to the bottom of this page (I mean the very bottom… all the way down) You will see a little “[kirupa.com](http://kirupa.com)” button with loads of little circles that look like they are blowing in the wind…

Its obvious this is tweening through a guide thats repeated… but I want a similar effect. With about 10 circles… I want them to vary in size and “\_alpha” on every pass and every time take a diffrent course from left to right… if it is even possible have them follow the mouse aswell.

Thanks again

Merry Christmas \<:}

I believe the button you’re referring to was done with actionscript and if you want to achieve that effect then you’re in luck cause theres a tutorial on this site for it. Here’s the link.
