Yeah, that's always bugged me.  I mean, Zen ideology is cool, and Buddhist stuff has always fascinated me, but as a tattoo it's a bit overdone.  Of course, that doesn't matter at all to everyone, and many Asian language scripts are absolutely beautiful.  But yeah, it's hard to "rate" something like that.  I mean, my next tattoo is probably going to be 
this (just the center design, not the words or periphery), so my idea of a great tattoo design extends a bit beyond just a symbol or two.  I've never been fond of smaller ones.  But that's totally a personal thing, doesn't make small tattoos less relevant for others.  I guess what I'm saying is the idea isn't up my own personal alley, but that doesn't actually mean anything.  So I guess I'm saying nothing.
Sorry, I'm tired.
And yeah Ghandi, that's pretty cool.  Visually I can't say I dig it that much, but it's certainly an awesome reason to get a tattoo and would certainly be something to treasure.
