MIXONIUM™ is a social media content management platform that allows for the intuitive and elegant co-mingling of multiple file types into a coherent post. The authoring and curation of the posts is made possible on any modern browser, and/or in a native iOS app. The system is based on a breakthrough "virtual shadow box" technology that makes it simple, easy, and fun to populate compartments with original material or pre-existing assets. File types easily managed into a post include: images videos, .pdfs, audio recordings, geoMaps, web links, advertising animations, 3-D assets, and transaction widgets. The result is a digital storyboard that is ideal for conveying concepts and exchanging information. Applications for this system range from education, retail, and business correspondence to entertainment publishing and consumer virtual scrapbooking.
