What we allow in is only the tip of the iceberg...which, I might add still reeks of repetitive dog nuts and ovate spheroids et al....but fortunately, thanks to moderation, Wincustomize.com is not literally swamped under the dross that otherwise would be the case.
Now, it is also important to note that although a wall here may possess artistic merit, this is not an art gallery, but a wallpaper gallery...an adjunct to the skins also provided.
If you want TRUE art 'variety'...50 ways to love your lever...then Devart caters for that.
If you want 'chick-walls' just do a Google for Britney.
Generally, apart from the odd dozen or so, the walls here are quite well executed....many exuding more intelligence than some of the downloaders...I still muse over the thought that 1300+ twits now have 'Still trapped in Bryceworld' on their harddrives...
