The Multiavatar Web-App is built around the Multiavatar Generator.
First of all, it's an interface for users to find and save their favorite avatars.
Additionally, users can generate and order unique merchandise using the Merch Maker, or pick products from the pre-generated selection in the Merch Store.
The Multiavatar app extends the avatar generator's functionality and it's also a way to monetize the Multiavatar service, without sacrificing free users' experience.
