Sorry for the inconvenience but unfortunatelly the MEGAVISOR.COM project is shutting down. For more than 5 years we've been trying to introduce, develop and promote the new kind of media content interaction. But, we have failed.
Catalog page, composer and other tools will be available for a month, until 8th April 2017. After this date all objects will be deleted, please prepare your sites for it.
