Hayao Miyazaki is the animation director genius behind Studio Ghibli and all its best movies. His first movie was a TV spin-off of Lupin III and is, by some way, the best Lupin III adventure produced. You can see all of Miyazaki’s enthusiasms and characterisation mannerisms even here in The Castle of Cagliostro.
The wallpaper is constructed from DVD capture but Lupin himself has been recoloured by hand to sharpen him up.
These two wallpapers are identical except the left one is encoded at JPEG95 and the right one as lossless PNG. The PNG definitely looks better but it is a much larger file size.
