I built a 3D flight route visualizer using Claude Opus 4.8, plan multi-stop trips on an interactive globe

Been experimenting with Claude Opus 4.8 (high effort) for building interactive web tools and this is the latest one, a 3D globe-based flight route visualizer. You pick your cities, it plots the route on an interactive globe and shows total distance, travel time, and layover duration. Built the whole thing with Claude handling the Three.js/WebGL work, which honestly would have taken me weeks to figure out on my own. Here's the tool: [https://vinish.dev/travel-route-animator](https://vinish.dev/travel-route-animator) Route in the video: New York → Dubai → New Delhi → Mumbai (14,614 km, about 35 hours including a 4-hour layover). Curious what features would make this more useful, airport codes, airline filters, fare estimates? Let me know.
