How to create miniature city magnets using Nano Banana Pro
What's the story
A new artificial intelligence (AI) trend is taking over social media, with people creating top-down images of their city's iconic landmarks as tiny 3D souvenir magnets. The trend was popularized by Google's Gemini Nano Banana Pro, an AI tool that demonstrated the concept earlier this week. The official account of Nano Banana Pro on X suggested users can create a knolling (type of arrangement) of a city's landmarks and asked them to request these as souvenir magnets for consistent look.
User participation
Prompt for creating miniature city magnets
The post from Nano Banana Pro also shared a prompt that users could replicate. The prompt reads, "Present a clear, directly top-down photograph of [CITY] landmarks as 3D magnets, arranged neatly in parallel lines and right angles, knolling." It further instructs to place the city name as a souvenir magnet at top-center and add a handwritten post-it note for temperature and weather conditions. Users have since been sharing their own creations featuring magnets of famous places from their respective cities.
Personal touch
User's experience with Nano Banana Pro
A user tried the trend and created a customized prompt for Delhi using ChatGPT. The result was impressive, showcasing landmarks like India Gate, Red Fort, Qutub Minar, Lotus Temple, Humayun's Tomb and Rashtrapati Bhavan as 3D magnets. The user also added elements inspired by Delhi's food and culture such as samosas or chai cups to make it more personal.
Trend appeal
Why people are drawn to this AI trend
The appeal of this AI trend lies in its simplicity and neatness. Knolling, which means arranging objects neatly at right angles, gives a clean and organized look to the results. Plus, the idea of turning landmarks into small magnets adds a fun travel-style feel. Users also enjoy adding weather-related items for sunny or rainy days, making each image feel more personal.
