with typography, check out this cool contest (some images NSFW) being sponsored by Type:

We would like you to design a tart card either for a typeface or a letter of the alphabet. If you are unfamiliar with these things, tart cards are the means by which London prostitutes advertise their services. Step in to any Central London call box and you can contemplate up to eighty cards inviting you to be tied, teased, spanked or massaged either in luxury apartments, fully-equipped chambers or the privacy of your own hotel room. So pervasive are these things, and so curious is their typography, images and copy writing they are now regarded as bona fide items of accidental art and have something of a cult following. Once on the periphery of design, the cards have influenced the work of many mainstream artists including Royal Academician Tom Philips and Sex Pistols designers, Ray and Nils Stevenson. Perhaps they can inspire you too? Maybe Sabon would invite you to caress its counters, or Palatino would advertise its ‘Mega Serifs’. Bodoni boasts some magnificent finials, Baskerville’s swash can really inflict some pain, and Century Schoolbook would undoubtedly keep you in after class. Perhaps you see something seductive in the curves of the ‘S’ or the ‘A’ exhibits dominatrix tendancies. However you see the alphabet there is a type-tart in every letter.

Dominatrix tendencies, ha! Pretty neat. (via)
