How about a mosaic picture frame for your dad's favorite picture or an art piece? You could also get a mosaic kit, so he can make his own mosaic art. Another idea could be taking your dad to a mosaic art exhibit or workshop in your town. And if your budget allows, you could hire a professional mosaic artist to create a customized piece just for him.
Or you can get him a star map with the date when he welcomed you in this world.
