An event may last for several hours. As such, it has a beginning a middle and an end. Planning the trajectory or arc of the event for your media will greatly contribute to the success of the event.
Though it is possible to pre-load all your content and let eObjx remix it through the night, why not consider staging when, how much and what content you should introduce into the mix during the event.
This, in conjunction with your guests contributions, can dramatically offer relevancy and excitement throughout the entire duration of the event.
eObjx will do the mix, you add the content fire and let the event ignite.
