Cube Portfolio can easily be modified to suit your needs to display any content you want (images, text, Youtube & Vimeo video, html5 self-hosted video, iframe content, etc.). Also, it has a built-in lightbox and full-screen modal popup (singlePage): check it by clicking on `view larger` or `more info` buttons when you mouse over the grid items below.
Don't forget to customize the plugin from the right side panel. ?
