Actually, some people, like DensetsuNoKaboom, are opposed to blood, so I intentionally left it as a red ring. I was going to get some CoD screenshots with blood splatter and put those on, but others may be offended.
However, I agree, the simple ring isn't all that visual.
BTW, how's your teacher's attitude towards guns and violence? You may or may not have seen my FPS (thread's titled "New FPS", but it's been here for a while now), and I have a course next semester on programming, where we will be using Alice to a limited extent (ha, I'll be off to a VERY good start). My school would probably prohibit the showing of my FPS, and I'm disappointed considering the amount of time and effort I have (and will continue to) put into it.
