ginormous wall = ginormous art

There is a ginormous wall in my living room that I am contemplating putting some ginormous art on. I'm thinking maybe decals? Did a quick search and these are my two favorites.

Minus the butterflies. This is from Walltat, and I love how sassy and bold it is!

I'm also a big fan of these circles from Funky Moose.

Rather than actually putting the decals on the wall, I think it would be cool to put them on a giant "canvas" kinda like in the first picture. I could use both of these and reverse them as the mood struck. Don't have a firm idea, but I'm toying with one :)
