Here at Metablocks, a huge part of our app creation is theming! In our latest Instagram Video Mashup (see our Metablocks list for more), designed for Enrique Iglesias, we've themed the app for FIFA 2014, with options for fans to choose their country to view country-specific Instagram videos in the mashup! Fans upload videos to Instagram with the hashtag #BailandoYourCountry (where "YourCountry" is the name of their country - for example, #BailandoArgentina), and will then see their respective videos included in the Bailando music video Instgram mashup for their country. (For a complete overview of this process, see our Application Overview article). You can check it out here: http://Bailando.enriqueiglesias.com/
