There is a popular piece of official and fan art showing the famous Akira pill as a standalone object, often on a red surface with the film's title.

If you meant a different "piece" — such as a music piece (the film's iconic "Tetsuo!" theme or Geinoh Yamashirogumi's "Kaneda") or a piece of merchandise — please clarify. Otherwise, is the most direct answer.

Visually, Akira acts as the definitive aesthetic blueprint for the cyberpunk genre. Set in "Neo-Tokyo," a megalopolis built on the ruins of the old city following a devastating nuclear explosion, the film captures the duality of technological advancement and spiritual decay. The city is a vertical labyrinth of skyscrapers, neon signs, and sprawling highways, yet it is populated by a disenfranchised youth, corrupt politicians, and religious zealots. The iconography of the film—the iconic red jacket of the protagonist Kaneda, the futuristic motorcycles, and the blinding glare of city lights—has permeated global culture, influencing everything from The Matrix and Stranger Things to the music videos of Kanye West. It presented a future that was both seductive and repulsive, capturing the anxieties of a rapidly modernizing world where tradition was being bulldozed by progress.

"Akira" has had a profound influence on the anime industry and popular culture. The film's visual style, which blends traditional animation with computer-generated imagery, has inspired numerous other anime films and series. The film's themes and characters have also been referenced in various forms of media, including video games, music, and literature.

Nearly four decades later, Akira retains a visceral power that modern animation struggles to replicate. It is a film that demands to be seen on the biggest screen possible, not just to appreciate the scale of its destruction, but to understand the intimacy of its craft. It broke the perception of animation as a trivial medium and introduced the world to the psychological depth and artistic potential of anime. Akira is more than a classic; it is a prophecy of the medium, a chaotic, beautiful, and terrifying warning from the past that still screams into the future.
