Print off logos, symbols, crests, or other images on cardstock (like the Harry Potter Gryffindor house crest), then string it on ribbon, or tape it with double-sided tape to make another bold, but simple statement.
Another great wrapping paper option is to recycle old comic book pages or nerd themed posters. These items are already visually interesting and make for a fun medium.
