Show HN: One-prompt slides (Gemini 3 and Nano Banana Pro)

Hey HN! I built this over a weekend after Gemini 3 and Nano Banana Pro dropped. Thought it would be fun to see if a simple pipeline could generate full slides from one prompt.

The setup is straightforward: Gemini 3 plans the deck, and Nano Banana Pro paints each slide as a single image: layout, text, visuals, everything. No templates, no manual tweaking.

It’s an weekend experiment, so plenty of rough edges: inconsistent styles, no fine-grained editing, and bugs probably running around freely. But it works, and it's free to try.

If you have feedback, ideas, or want to roast the approach, I’d love to hear it. Just exploring whether this is worth taking further.
