All Tomorrows is a work of science fiction written and illustrated by C. M. Kosemen.
The book explores a future path of human evolution through genetic engineering. Essentially, the illustrations and descriptions chronicle how a conquering alien population has engineered humanity into many new species.
This work has always fascinated me, especially from the perspective of posthumanism and transhumanism, even though it is a less theoretical and more whimsical take on those ideas.
All Tomorrows has never been formally published but has gained a life of its own through the internet which is another reason that it intrigues me so much.
