This new app, the appropriately-titled Tunnel Vision, makes New York City subway maps move in a trippy fashion. 

After downloading the app, you point it at a map and the image begins moving upon recognition. The movement you see here uses turnstile data to give a representation of people entering and exiting a train station in real-time. 

Speaking of real-time movement, you also have the option of watching trains travel that way, or viewing the population density and median rent at a given subway stop. Granted it'll feel like you're hallucinating, but it makes the experience of traveling on the NYC subway more interesting, which, believe it or not, is actually possible.
