Yup, it's Dev the Chameleon again! He's the neurotic, passive-aggressive, paranoid skinnable mascot!
why would he made a good mascot? he's instantly identifiable, he's likeable (er, sorta), and he has
a personality. since he's "skinnable", his style, look and colors can be altered to suit the needs of deviant art - from b&w line art, to a monochromatic tone or even (in an unlikely event of plug-in misuse) a rainbow of colors. heck, he could be a changed to a gender in-specific "it" if you wanted too.
