It's a visual...basically lots of pows in a kind of circle! -i- s-o-t-r .
By the way, on another note, when I googled this, it appears that it has already been answered. However, when I'm directed to this site, the page that opens does not contain my Q or the answer to it. I'm relatively new to this site, so can someone tell me where ye hide previoulsy answered Qs around here?!!
