LUNA is designed to support a wide variety of file types, including content from video sharing sites like YouTube and Vimeo, as well as other URL-based content. Treating URLs as objects in LUNA empowers users to add diverse content to LUNA collections. If a browser can render it, then LUNA can display it.
To achieve this we enhanced LUNA to handle .html files so that content loads in the Detail View. In addition, you can add a custom thumbnail to represent your html content in the Viewer. Now you can add videos, 3-D models, even whole websites to your collections.
