You can also get the raw psd file for all the variations of mirai-chan illustrated by Tasuku Iizuki-sensei complete with logos.
Inside the PSD file you will find layers for various facial expressions and all her uniforms. Feel free to use for non-commercial purposes (wallpaper/stickers etc).
Maybe you can make some wallpaper and upload to devientart or pixiv!
Would be great if some folks can make some Android, iPhone, iPad and other wallpapers too! If you do then just provide a link to http://mirai.fm when uploading - then leave a link in the comments below to your work. Cookies available for folks who come up with exceptional designs!
