This tablet attachment has the power to transform your ordinary iPad into a holographic projector. Using a clear “synthetic” mirror hinged at an angle, the Holocube HC Tablet reflects the media from the iPad, creating the illusion that it’s floating in thin air. The Belgium-based Holocube team and lead designer Joris Vanbriel have also created aprojection-in-a-box platform that uses the same technology as the tablet.
