To create a Gamecocks background vector wallpaper, you can use the @mapbox/vector-tile and geojson-vt packages. Here's a brief snippet to get you started:

import { VectorTile } from '@mapbox/vector-tile';
import { sliceGeoJSON } from 'geojson-vt';

// Load your Gamecocks data in GeoJSON format
const gamecocksData = /* load your data here */;

// Slice the data into vector tiles
const tileLayer = sliceGeoJSON(gamecocksData);

// Create a VectorTile instance
const vectorTile = new VectorTile(tileLayer);

// Use Expo's Vector Icons package to display the wallpaper
import { View, Image } from 'react-native';
import { VectorIcon } from '@expo/vector-icons';

const GamecocksWallpaper = () => {
  return (
    <View>
      <Image source={{ uri: vector-tile://${vectorTile.url} }} />
    </View>
  );
};

This code assumes you have the necessary data in GeoJSON format and uses the @mapbox/vector-tile package to slice it into vector tiles. The resulting wallpaper can be displayed using Expo's Vector Icons package.

Note: You'll need to replace the /* load your data here */ comment with your actual Gamecocks data in GeoJSON format.
