"π", also titled "Pi", is a 1998 American surrealist psychological thriller film written and directed by Darren Aronofsky.
This poster was designed for and gifted to someone who shares my enthusiasm about the film. When fixed on the wall, seems just like a spiral made of random numbers. After backing up 2-3 meters, you can start seeing the images. On the other hand, getting up closer will reveal the first 20.000 digits of the number "π".
