Reading Vision Simulator: Focused Mode

Warning: this mode is not for the faint of heart. In this mode, the words will appear at a rate of 300 wpm, with a 10-second delay between each sentence. Your eyes will water, your brain will burn, and your productivity will suffer.

Features:

Settings:

Relaxed Mode (because who needs focus, right?) Paranoid Mode (where every sentence is a red flag)
(Note: The JavaScript in this code is not fully functional as it is intended to be a starting point for the simulator, and will need further development to be fully functional.)
