Text Generate Effect

A cool text effect that fades in text on page load, one by one.

Oxygen gets you high. In a catastrophic emergency, we're taking giant, panicked breaths. Suddenly you become euphoric, docile. You accept your fate. It's all right here. Emergency water landing, six hundred miles an hour. Blank faces, calm as Hindu cows
