Lain wallpapers from the anime?

I been searching for a Lain wallpaper I like for some time now. The images I usually found, aren't quite what I want. I think some parts of the anime are interesting for wallpapers, but of course the quality is not too good. Nonetheless, I extracted all the keyframes from the videos and selected a few images I like. Maybe some one can help me to find similar images with better quality? Or maybe the images can improved? For those interested, I used ffmpeg with the following script to extract the keyframes: for i in $(seq -f "%02g" 1 13) do mkdir lain$i INPUT="Serial Experiments Lain - E$i.mkv" OUTPUT=lain$i/lain-e$i echo $INPUT -- $OUTPUT ffmpeg -loglevel warning -i "$INPUT" -vf "select=eq(pict_type\,I)" -vsync vfr -qscale:v 2 -huffman optimal "$OUTPUT-%02d.jpeg" done

Is it possible to make them into a higher resolution?

>>1995 Check out this project for upscaling vectorisable graphics https://github.com/nagadomi/waifu2x demo available here: http://waifu2x.udp.jp/

>>1995 I can upscale then, but there is no point, the images wouldn't have any more details in them... >>1997 I tried the demo, but images weren't any different than what one would get with normal upscaling. Maybe it's intended for images of lower resolution... I have the hope that better quality versions were available some where. Particuly of the image show at the ending. I like that image but its too blurry. Maybe I should the check the possibility of vectorization.
