This one could be really neat, either as a Father’s Day gift idea, or just a wonderful creative endeavor for your geeklets at anytime. Tikatok is an online tool/service/creative community that allows kids to virtually assemble their own books and have them printed, either for themselves or other friends and family.
Obviously this is not unlike other print-on-demand services around the internet, but I like the kid- and family-focus, and the enrichment it could offer to a child to have something they create assembled into something they can hold in their hands, or bring to preschool and share with their friends.
