This one was actually a lot of fun to do. It’s full of weird little doodads and patterns in-between the maze pathways. You can see the process in the video here. That creepy little face on Cape Cod was completely incidental.
The maze starts on I-90 coming from NY and ends on Cape Cod (reverse that for an even more difficult maze).
The song is by Chris Zabriskie from his Undercover Vampire Policeman album.
