Hobo Code by Colleen Heslin I still really want a stick’n’poke of John Hodgman’s “the hobos will rise again” hobo symbol (H with rays. so beautiful.).

tktktktktk: A hypothetical conversation between me and someone with a tattoo involving either hobos or their code: “What’s your tattoo mean?”“Oh it’s the hobo-code symbol for tree phone”“That must really have some meaning to you”

Did this for my Dad's 59th B-day, used free software to record and free color editing program to change the color of the background and wave, even uploaded the actual voice clip of me wishing him a happy birthday then put a QR code linking to the sound clip on the back of the frame. Whole gift was free minus the frame and he absolutely loved it! :)

Have your husband say "I love you," record the sound wave, one of a kind art piece. - I would do this for first sonogram with heart beat
