The Theme for Fantasticon 2019 is A F R O F U T U R I S M !
Wikipedia has this to say: Afrofuturism is a cultural aesthetic, philosophy of science, and philosophy of history that explores the developing intersection of African/African Diaspora culture with technology. It combines elements of science fiction, historical fiction, fantasy, Afrocentrism and magic realism with non-Western cosmologies in order to critique the present-day dilemmas of black people and to interrogate and re-examine historical events. It was coined by Mark Dery in 1994 and explored in the late 1990s through conversations led by Alondra Nelson. Afrofuturism addresses themes and concerns of the African diaspora through a technoculture and science fiction lens, encompassing a range of media and artists with a shared interest in envisioning black futures that stem from Afrodiasporic experiences. Seminal Afrofuturistic works include the novels of Samuel R. Delany, Octavia Butler, Nalo Hopkinson, N. K. Jemisin, and Nnedi Okorafor; the canvases of Jean-Michel Basquiat and Angelbert Metoyer, and the photography of Renée Cox; the explicitly extraterrestrial mythoi of Parliament-Funkadelic, the Jonzun Crew, Warp 9, Deltron 3030, Sun Ra, and Janelle Monaie; and the Marvel Comics superhero Black Panther.
