How can I make tiles transparent?

[Nucleotides Assembled]

The title says it all. How can I make tiles transparent? I know, I know, some tiles are already transparent and therefore I can see my background wallpaper. But some tiles like Nokia Camera, Facebook are not.
Is there anyway/any app I can download to make those non transparent tiles transparent so that I can see my background wallpaper more?

Thanks.

Thanks. But that app is paid. I saw a free one called Transparent Tiles Maker. It replaced some of my opaque tiles with transparent ones but I am still looking for a free app that can replace the opaque Nokia Camera tile and New Post tile.

Why don't you create a live folder with both apps in?
Live folders are transparent...

Live folders have those inner small animating tiles, so not 100% transparent.
