Not sure where these Avatars came from but it seems that somebody got creative with Photoshop and used layers to create some holographic BBM avatars. When you look at them at first the avatars appear normal but when you click on them you see them change into a super hero or other type of image. I noticed earlier some of my contacts all of the sudden kept changing their avatars into a Superman or Spidey then Ronen sent over a link to CB where you can download some of this images right from your BlackBerry.
If you want to try them out for yourself follow this link. There is quite a few different ones including pink avatars for the girls.
