RE:ARHT Media Signs Deal to Bring Holographic Display TechThis is great news and hopefully the first of many retail Point of Sale advertising display deals. I believe this to be the "Killer App" for ARHT's technology. Interactive 3D displays to attract and engage customers, offering them discount coupons to their phones etc... It would be ideal if the 3D display could be combined with a commercial scent machine to enhance the experience. Imagine in this cannabis case, a sexy male or female product user blowing a puff of smoke at you in 3D combined with a slight (not too strong) scent of marijuanna smoke. Or... A 3D rotatiing McDondalds Big Mac display in a Subway staion emitting the pleasant aroma of a Big Mac just before lunchtime :-) You walk up to the display, scan a barcode and get a 2 for 1 coupon sent to you phone !! Nice !!
