Well... I'm a YTMNDer... I admit it. I love the site, and spend far too much time it. I never submit anything, just brows, *FAV!*, rate, and sometimes comment.
This wallpaper is a collage of different YTMND fads made by someone from YTMND, can't remember who exactly and don't feel like looking it up.
Oh and for those of you who don't know what YTMND is go here: [link]
