LOVE! It's an oldie but a goodie, artist Olek takes on Wall Street. Olek is a New York based Guerrilla artist who specialises in yarn installations and sculptures. Except her work is anything but twee. Her best known pieces include covering the Wall Street bull with bright pink crochet in the dead of night and an apartment where the residents and contents seem to be made entirely of yarn. Unfortunately the Bull installation was taken down within hours but she did make this video - perhaps knowing that it wouldn't be allowed to stay.
