Prompt code:
A 2D flat book cover design with an abstract style and a central spiral motif. The spiral starts with thick, bold lines and gradually becomes thinner and more intricate towards the outer edges. The color scheme transitions from deep copper tones to electric blue. Subtle silhouettes of communication devices from different eras, including an old radio, telephone, computer, smartphone, and futuristic IoT symbols, are overlaid on the spiral. The title is in a sleek, modern font and is positioned diagonally across the cover. The background is a minimalist design with faint circuit board patterns.
