Meaning Seeking Animals

As a result, the publication borrows from cartography, as it sets the reader adrift on a topographic map of sentences and paragraphs “as it is high time for cartography to take its place among the arts and for the atlas to be recognised as literature, for it is more than worthy of its original name, theatrum ordis terrarum, the theatre of the world”.

Poetics and Politics of Erasure

Poetics and Politics of Erasure is a multidisciplinary essay on the aesthetics and politics of erasure. The framework for erasure is drawn from a critique of accelerationism, the video game Katamari Damacy, and internet aesthetics. It begins by investigating power relations in dominant archival practices, before tracing how memory storage technology (from the written word to the internet) reinforces hierarchical models of knowledge, and finally posing the generative potential of erasure in alternative models of knowing, doing, and being. It does so by locating strategies of erasure in audio, visual, and digital cultures in the forms of: erasure/forgetting, translation/mutation, and recontextualizing/remythologizing. oneacre.online had a small feature in the Sonic Acts Academy book.
