Its see-through display can be viewed from any angle, and its audio system incorporates two full-range drivers and a subwoofer. Sign up to be notified of the Kickstarter launch here.

Kings Wild Project’s money-inspired playing cards features intricate drawings that look like banknote engravings. Artist Jackson Robinson’s imagery is embellished with a foil printing technique that gives this deck and its box a shimmery holographic effect that mimics the anti-counterfeiting tech used in modern paper currency.
