Yes! Big Screen Social has been designed to work perfectly on a landscape or portrait screen. The display will change according to the screen you use (eg. TV or computer screen or tall Totem display screen).
Landscape: The image/avatar is displayed on the left, with the text to the right of the image (as shown in the demo video)
Portrait: The text will be displayed underneath the image/avatar.
Both versions use a flip-book like transition between each post (again, as shown in the demo video).
