How about getting him a virtual reality headset or upgrading the one he currently has? Another idea could be to get him a VR game he's been wanting to play or a subscription to a VR gaming service. Additionally, you could plan a romantic virtual reality date night where you both explore destinations in VR together.
Or you can get him a star map with the date of your anniversary.
