I'm going to paint the little target guys on the ground with TS-8 Italian Red, TS-18 Metallic Red, and TS-11 Maroon. If you mix it up enough before the spray it looks just like recently coagulated blood.
I was recently toying with some simple animatronic stuff based off watch batteries, and I might be able to make the plastic people 'squirm' if I wire it up right..
And I found these cool RPG scale model toys at Hobbytown..
I'm going to paint them like cameras for my reenactment.
