Do the cool kids still call them wallpapers? Regardless, this is a link to roughly 100 absolutely stunning Studio Ghibli wallpapers. Be wary: you may be tempted to buy new computers just to use all of these images because they are gorgeous.
I didn't have the bandwidth to go through all 100, but I've already gone ahead and made the Ponyo one above my work desktop image -- mainly because I like some clean space to drop files on when I'm being lazy as hell.
There is a lot of gorgeosity here that's for sure.
