Taking Yesterday Makers for a Spin Brains and #timetravel. The cover of my #sciencefiction book Yesterday Makers, with the atomic brain rotating in a night and day effect. #novella A video posted by Russell Kightley (@russellkightley) on Jan 8, 2017 at 3:39pm PST I have enlivened the cover of my novella Yesterday Makers by spinning the atomic brain.
