Challenging the long-held belief that one surface could produce only one hologram, Faraon's team created a surface from tens of millions of silicon nanoposts of varying shapes and sizes. Together, these nanoposts can project two different holograms based on the angle of light hitting them. 

This feat opens the doors to new innovations in various applications, including virtual realty. Read more here
