This is a fun video about a machine that I had never heard of before. It's a marker that sounds like a woodpecker and uses a pointed pin to create artworks. Vevor set me up with an account that allows me to request samples for a video and this was something that I didn't know I needed before this video. Warning it may give you a headache. I would recommend a clear coat on the tags for long life.
