The Gallery of Babel is a virtual gallery that contains all images.
This means every picture you will ever take or see, or that will be ever taken of you is somewhere in this gallery.
There's even pictures of you and I together!
If you want, you can upload a picture and it will take you to where it is in the gallery.
Actually, this gallery only contains RGB8 images that are 256x256 pixels in size.
This means that there are exactly (2563)256 x 256 images. That number is approximately 1.75024978 x 10473479, which means the number of pictures that are in the gallery has 473479 digits! If you want to see the exact digits of the number, click here (warning: the number is really big).
Obviously, the images aren't really there, since the gallery is not a physical place, but a virtual one.
However, wherever you are in the gallery, it's possible to walk to any of the other images using just your arrow keys.
Beware, though, that you (and the universe) would be dead many times over before you reached it.
The gallery requires a browser that supports webGL2.
