Japanese Twitter user @Kya7y recently discovered a breathtaking gem from her father's past — a hand-drawn, incredibly intricate maze that he created more than 30 years ago. According to Spoon & Tamago, the father spent a full seven years drawing the maze by hand, sketching in each detail on a single sheet of A1-sized paper, measuring 33 inches long and 23 inches wide. It's not clear whether he based his design on anything in particular, but @Kya7y says she's already received plenty of requests for photocopies.
