Inspire a techno dark cover album design featuring an enigmatic, pulsating cityscape under a moody, starlit sky, where towering skyscrapers cast long shadows on slick, neon-lit streets. Add an abstract, floating geometric shape above the city, glowing with an ethereal light that hints at dimension-shifting energies. The overall atmosphere should evoke a sense of mystery and draw the viewer into a world where technology and imagination intertwine seamlessly, inviting deep contemplation and immersion.
