Hapax Phaenomena is a collection of historically unique images discovered by Google image search from collaborators Clement Valla and John Cayley. The fragile and tenuous Phaenomena are organized into subcategories within the five folders; 1_discordant_wonderfulness; 2_nondurable_megabyte; 3_inventive_monetarism; 4_patriotic_leaseback; and 5_diatomic_roach. Each Phaenomena is accompanied by a certificate of authenticity, a screenshot of its moment of global and historical singularity taken by one of the artists.(Source: Rhizome project description at The Download)
