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.

Unsure what to do with the discovery, @Kya7y reached out on twitter but was quickly inundated with requests to receive copies, which is now available here.
