BTW, the Harry Potter icon belongs to shadowshamrock
She actually has a tutorial on how to make those little animations on the side, but I couldn't follow. So does anyone else have any other technique on how to put little animations on the side of an icon?

I just want to know how you put those little dots on the Pop art picture, I know you can do them in PS via filter. I pulled it off once, it's just that I don't know how you do that anymore... 

PLease I'll be so uber happy if anyone can help!!
