This is a modernized rebuild of one of my first three.js projects.
The web/advertisement company I was working at had recently made a contract with a sports stadium, selling advertisement spots on their LED banners and offering their services to create videos and static banners for those.
When we extended our website to include the new service, we added the original demo that I'd started as a lunchbreak project, for clients to visualize the spot they'd like to purchase.
