A pair of Singapore buildings are once again in the international spotlight after a photo producing a cool illusion was posted on the global Reddit community.

The subreddit is a forum that is dedicated to things which are, well, mildly interesting.

Users usually post images of novel and trivial things, ranging from a woman in the window reading the book called A Woman in the Window, to intricate ancient keyholes.

Optical illusion confusing Reddit users

The Gateway are a pair of 37-storey complex comprising two buildings -- Gateway East and Gateway West.

Designed by a world-famous architect

Completed in 1990, The Gateway is located along Beach Road, across from other famous skyscrapers such as the DUO Tower and Parkview Square -- otherwise known as the Batman Building.

It was designed by I. M. Pei, the world-famous architect who also designed the Louvre Pyramid in Paris and the OCBC Centre in Singapore.
