How about commissioning a custom abstract painting from a local artist or finding a beautiful one at a gallery? Another idea is to buy him a set of quality paints, brushes, and canvases so that he can experiment with painting his own abstract art. Alternatively, you can also look for an abstract painting workshop in your area, where you can sign up for a lesson for the two of you to create abstract paintings together.
Or you can get him a star map with the date of your anniversary.
