The video shows Bin contemplating a tablet-sized touchscreen device before quickly turning it on its side, taking it into landscape orientation, where he performs the party trick — folding two panels of screen, one at each side, back behind the tablet to form a slightly chunky looking phablet.

When the video cuts back to the front there’s a slight spinning of the screen, as the software appears to grapple momentarily with the new form factor, before it stablizes in portrait orientation.
