"3D door model with the pattern of Minimalist graphic symbol inspired by the movie 'Oppenheimer.' A sleek mushroom cloud at the center, abstracted into smooth, geometric curves. At the base of the cloud, subtle atomic elements like a small dot or an orbit line suggest scientific precision. A thin clock hand extends from the middle of the design, merging with the shapes to symbolize time and destruction. The design uses bold flat colors--black and white with a red accent for tension. Clean, modern, and balanced, with a focus on simplicity and negative space."
