You try and connect the signs in your head, but it just looks like a funny zig-zag line. But you soon notice that the pattern repeats itself every so often... Every 11 signs, in fact. It is worth noting that the vast majority of the signs are on your right side, with only one on the left out of all eleven. The ones on the right side are varying distances from the wall, with the distances as follows:
>Sign 1 - 2 feet
>Sign 2 - 3 feet, 1 foot from Sign 1
>Sign 3 - 2 feet, 9 inches from Sign 2
>Sign 4 - 2 feet, 1 foot from Sign 3
>Sign 5 - 1 foot, 3 inches from Sign 4
>Sign 6 - 8 feet (1 foot from the left-side wall), 4 inches from Sign 5
>Sign 7 - 0 feet (against the right-side wall), 4 inches from Sign 6
>Sign 8 - 2 feet, 4 inches from Sign 7
>Sign 9 - 2 feet, 1 foot from Sign 8
>Sign 10 - 3 feet 3 inches, 1 foot 3 inches from Sign 9
>Sign 11 - 2 feet, 6 inches from Sign 10
>The pattern repeats itself after several feet between each Sign 11 and Sign 1. With so many signs, you're having trouble visualizing it the pattern as a whole...
>Futahime: Mark other signs uniquely, like Sana did, to help make sure there isn't some sort of illusion/teleport maze involved in this mess.

Keep drawing hats on signs. They're classy!

You draw a bowler hat on a sign! Jan see what you and Trance are doing, so she draws a musical note on another sign. Nothing seems to happen.
