I chanced upon a video of an artist's work, Olivier
de Sagazan, who uses clay and paint to transform himself into some hideous incarnations during this freak-out performance:

While fascinating/disturbing on its own for its artistic merits, it made me think of a Chaos-inspired mutation. Any one of the 'modes' that this guy creates could make an awesome miniature, some primal nastiness, hence my posting this in painting/modeling. I doubt the guy's ever heard of
40K but I respect the work for it's visual ghastliness. Kind of like a David Cronenberg-type thing.
I may actually try to sculpt out a few figs based on this random scary-face-mask type theme.
