Remember years ago when EVERYTHING had a lunchbox?
Anime is the lunchbox of the next generation. So is video games.
As for the designs in the post itself, I thought it was a cool concept. I watched Rugrats when they had the special episode where they were all older (the only episode I voluntarily watched), but apparently 'Rugrats' are now permanently older.
I laughed at the fact that Charlie Brown still had his hair issues, but wasn't incredibly impressed beyond that, just interesting to see how this artist thinks they would look as older people.
