A Chicago woman's unusual tattoo isn't just a visual reminder of her late grandmother - it also plays the woman's final voicemail.
The woman tweeted a video showing the tattoo under her left collarbone as it was scanned with a smartphone app.
The app then played the last voicemail the woman ever received from her grandma,which was a happy birthday message from three years ago.
She tweeted, "My grandma passed away my junior year of high school. A month before she passed, she left me a voicemail wishing me happy birthday. Today I got that exact waveform tattooed across my heart, and I am able to play it just by holding my camera over it."
The tattoo and app use Skin Motion technology, which allows a user to upload an audio file and have it play whenever the relevant "Soundwave" pattern is scanned with a smartphone.
