(note to self - must remember to etch her a message on the PCB somewhere too, chicks love that sorta thing)
Store a few messages in the mcu and display a rolling image of them from time to time (at the hour, on alarm, etc.)
You will score lots of points with her.
Hehehe - yep, definitely. It'll be a little limited given I've only six 7-seg displays to work with. There's about a digit's worth of empty space between each pair of digits, too; I wonder whether scrolling messages will work best if I ignore the gaps (ie treat it as a 6 digit display) or if I pretend they're there (treat as an 8-digit display, so characters disappear behind the gaps)... Got until Christmas to suss it all out though
