This 3D Version of Tokyo's Subway System Looks Like a Labyrinth of Roller Coasters:

…by creating a 3D model of Tokyo’s tangled subway system, one which has brightly colored tubes swooping up and down, running over and around each other like the tracks of one of the craziest roller coasters ever.

I’ve appreciated the scheduling efficiency of the Tokyo subway system in the past, but this 3D impression of how all the lines interact is something else.
