Write her a love letter, with a calligraphic pen, on real parchment paper. (You can pick the supplies up from Office depot.) If you want to get really fancy, get a matching envelope, and seal it with wax.
If you want to be really classy, have a bunch of flowers delivered to her house. Bringing flowers is fine, but having them sent drives girls nuts.
If she frequently listens to a radio station that does requests, call up and dedicate it a song to her.
Just some ideas that came to mind. Carry on.
If only you and dead people can read hex, then how many people can read hex?
