Abstract
A mobile hologram apparatus is disclosed. An example apparatus includes a sheet folded along preformed creases into a pyramid structure configured to be actuated between a compressed state and an uncompressed state. The pyramid structure has a base section and a top section connected by four side sections. The pyramid structure in the compressed state has a height that is less than 1/10th the height of the pyramid structure in the uncompressed state. The apparatus also includes an elastic band connected to a perimeter of the base section of the pyramid structure and configured to cause the pyramid structure to self-actuate from the compressed state to the uncompressed state.
