Indeed, here is another Gurren wallpaper. This one features Nia once more, it would seem. I'm not used to producing such bright, sparkly, "pretty" things...but she is a princess, so it seems suitable. (I'm not overly fond of pink, but her colour scheme forced my hand.)
Also, as a special gift to everyone, this wallpaper comes in wide, tall, and normal versions. I wanted to make a PSP-sized (480x272) version as well, but putting the low-contrast menu area on it is a terrible chore...sigh.
