A light, blurry Chinese painting with Japanese calligraphy instead of the standard icons. Created with KSplasherX (thank you XaniloM!) Currently in 1680x1050 resolution; if this doesn't work for you, I'll be happy to convert it to a different size.
NOTE: For some reason, the preview is always cut off. But when I test it, it is fine.
