Of the fantastic pictures so far, I like #18 the best. (I thought this before reading anyone elses preferences)
What I'd like to see to compare is one with the background text rotated in a single direction only, like the / slanting text in #19, with the same contrast used for the background as in the / slanting text in #19, but with the size of the background text half way between that used in #18 and #14 Fussy eh? Oh well ... I own a T-shirt with "indulge me" written across the back of it :-) Stephen.
