Create a retro-themed poster background with a dark color. Add neon elements like glowing geometric shapes, grid patterns, and retro items like cassette tapes, vinyl records, and arcade machines. Use bright neon colors like pink, electric blue, and neon yellow. These elements should be scattered around the edges, leaving a large empty space in the center for text. The overall vibe should be reminiscent of the 80s, with a fun, energetic feel that captures the essence of a retro party.
