Magician Norberto Jansenson published this video over two weeks ago, but it has only begun to trend over the past weekend, quickly amassing over 150,000 hits

The video is titled Azulejos, which is a Portuguese ceramic tile work, and features the magician slowly moving around the shiny tiles that make up a larger rectangle. After seemingly reforming the same 9×7 shape, he comes up with an extra tile.

And another. And another. What is this sorcery?
