There's some updated designs I made in the Photos section. There's a
front logo and a back logo. Of course, the bright red circle (with
tiger) makes a good target for somebody to punch, stab, shoot you.
Though it kinda might look kinda cool.

Also, since the bright red tiger might be a little too much color in
one little circle, (well, mainly 'cause it looks like a bulls-eye
target) I might put the tiger (smaller) on the front and replace it
with the Japan Karate flag-ish logo (you know, where the red dot is
above the middle of the white circle [if you know what I mean]). It
still would look like a bullseye of course, but since the red dot
isn't in the middle, it'd kinda takes that assumption away.

Anyway, what I'm trying to say is, check it out!
