i've been a fan of cut-ups ... like bourroughs did (with writing) but with film,
taking a roll of film and shredding it / cutting it up, then a putting it in a RANDOM pile ( flat or no so flat )
and making contact prints / photograms from that /// water damage always does great stuff ... just leaving film in a puddle of water or
having drips of water on it to eat away at the emulsion ... or print through the film with something on it
unfortunately rubber cement, acetone, varnishes/urethanes, paints, waxes, collodion and similar slurries are flammable
so if you go this route, you have to work fast before you have something like a movie-house fire in your darkroom
