In this short February 2026 video, Matthew Berman highlights a flocking visualization and an urban-planning app presented as created with Gemini 3.1 Pro. He admires the city layout around geographic features; the video does not independently assess its accuracy or suitability for real planning.

- 2City-planning appA second example depicts a city being arranged around geographic features.
- 3A gaming comparisonBerman wonders whether such simulations suggest a future direction for city-building games.
Takeaways
- The first example shows a flocking simulation attributed to Gemini 3.1 Pro.
- A second demonstration visualizes city layouts around terrain and water.
- An appealing demonstration alone does not establish real-world planning accuracy.

Visual simulation
Berman introduces a flocking example.
I show a flocking simulation presented as written by Gemini 3.1 Pro. The demonstration is visually striking; the displayed material describes the images as illustrative, so it should be read as an example rather than a benchmark of the model.
Simulating city planning
He shows a city layout and compares its potential with city-building games.
I then show an urban-planning app presented as created with Gemini 3.1 Pro. It visualizes a city around a geographic landscape, including paths, water and land features. I admire both the function shown and its appearance, and wonder whether this points toward a future for games like SimCity. The short clip does not evaluate whether the plan is realistic or suitable for actual construction.
