That is at least the opinion of the project founders behind Holix, a speaker with a holographic display that is currently seeking backers on Kickstarter. Behind this name hides a speaker with a 3D holographic display intended to make music visible - or so the project founders promise. The most important feature, however, is likely the holographic display, which is generated by two rotating LED strips. For example, the "5D Holographic Speaker" is offered on Amazon for a price of around $90 - without any crowdfunding risk. Those who can live with somewhat stripped-down specs (such as a slightly less powerful speaker and a lack of NFC functionality) will find a visually similarly (un)appealing device here.
