How about a painting workshop where your dad can learn how to create his own abstract paintings? You can research for local art schools, museums or art centers that offer such workshops. If you’re on a budget, you can buy him a set of painting supplies, canvas, and some instructional books on abstract painting. You can also try looking for an abstract painting that you think would fit well in his home or a coffee table book of famous abstract paintings.
Or you can get him a star map with an important date you share.
