Whoever made that website needs to optimize it a bit, I'm on a fast connection and sat staring at an empty page for minutes until it finished downloading all the unnecessarily-large megabytes of images.

"Bionic Reading is a new method facilitating the reading process by guiding the eyes through text with artificial fixation points. As a result, the reader is only focusing on the highlighted initial letters and lets the brain center complete the word. In a digital world dominated by shallow forms of reading, Bionic Reading aims to encourage a more in-depth reading and understanding of written content."

A lot of words for "we set the first syllable of the word in a bolder version of the font"
