This is a slightly reduced version of Wikipedia - Grey Lady , primarily intended for those who wish to load the style as a script. Apart from making it available to non-Firefox-browsers, it may also be a good FF option too, as large pages feel decidedly less sluggish this way. It is, however, a fairly large and unwieldy style sheet and the script does not seem to produce the desired results as consistently as Stylish's implementation.
NOTE: Just tried this in Opera... Not pretty :( Dunno about Safari...?
