Some people have hobbies. Other people are obsessive. But when the two cross paths, this is what you get.

Japanese twitter user @Kya7y recently unearthed an incredibly detailed maze that her father created almost 30 years ago. When pressed for details, the father explained that he spent 7 years creating the map on A1 size paper, which is about 33 x 23 inches.

People have been asking @Kya7y about her father. Everyone seems to want to know more about the man behind this amazing maze. This morning she wrote, “Where does my father work? At a public university!! In the athletic department!!! As a janitor.”
