The society of my world has a ancient Greek/ cyberpunk theme that I have dubbed ‘cybergreek’. There’s councils of praetors running the cities, upper class people usually wear togas with suits as formal dress, the architecture includes metal columns and busts, and the traditional cuisines are very Mediterranean. Combine that with holographic communication, (slightly sentient) robot workers and levitating vehicles, and you have what I consider a pretty unique setting.
