Wordema shows At the Earth's Core one word at a time, each word held at the same fixed point on screen so your eyes never travel. This is called RSVP — rapid serial visual presentation. You set the pace, how softly each word dissolves, and how long the reader pauses at commas and full stops. Nothing to install, no account needed, and your place is kept.
At the Earth's Core is in the public domain and free to read in full. The text comes from Project Gutenberg.
