I really liked Sixteenbit's model, but wanted color on the back - and I was more than a little inspired by his “clean” model.
Anyway, I copied, dropped, subtracted, copied again and dropped the blood down again in five minutes of 3D Builder action, and am happy enough with the results to share it.
It's tempting to make the levels raised though it would be less good for a coaster.
The author remixed this model.
