This afternoon, I suddenly had an inspiration and spent 5 hours creating a small tool — a generator that automatically produces beautiful mobile wallpapers based on selected cryptocurrencies.

It's quite interesting. When I first discussed the requirements with AI, I was very clear: it should allow users to choose different coins, automatically incorporate the coin logo into the wallpaper, and ensure aesthetic appeal. After a few rounds of conversation, the requirements were basically finalized.

The technical solution uses Gemini 2.5 Flash for image generation, with the backend connecting to the CoinGecko API to fetch coin data and information. The most interesting part is the artistic style — tone adjustments, font standards, visual hierarchy — these details need to be carefully refined to make each coin's wallpaper look professional yet unique.

The whole process was quick but also tested the limits of imagination. From requirement clarification to parameter fine-tuning, it was almost a seamless flow. Now, this tool can stably generate wallpapers themed around various cryptocurrencies, and I feel it can be further optimized and expanded. Interested friends can give it a try and provide feedback on the results.
