Ever accidentally typed bing in spotlight while trying to access Microsoft Edge Dev to use the new Bing chat assistant and not had what you expected happen? Simply clone this repo git clone https://github.com/lehmacdj/Bing.app /Applications/Bing.app and then rebuild the executable Contents/MacOS/Bing if you're using an Intel Mac (I have it checked in pre-compiled for arm based Macs). Now you'll have Bing.app available as a search result in Spotlight and will be able to open Bing with open -a Bing from a terminal too.
Run bin/make_icns.sh from a directory containing BingLogo.svg to generate a new BingLogo.icns. Use it as the new app icon by replacing Contents/Resources/icon.icns with the new file.
