These cuff links, fashioned from the keys from an old keyboard, would make a perfect little present for the geeky love in your life. (Provided he or she has shirts with French cuffs. And if they don't, buy one of those, too.)
They're only $9 on Etsy, but the crafter doesn't seem to let you select the keys you want to use, which would be absolutely essential to me. I'd suggest pinging the crafter "BeaG" and seeing if they can do a custom job for you. Despite being based in Belgium, BeaG should have just enough time to turn something around by Valentine's Day.
