Typewriter Text with Underscore that types and erases (In a Cycle)

I found an amazing typewriting effect at this website: http://www.9elements.com

The header shows a brilliant typewriter effect that I want to duplicate,开发者_JAVA百科 but the code does NOT work in Explorer. The script types each letter, erases it via backward delete, and then types the next sentence separately. More importantly, it loops.

I need to find a script that is comparable if not the same.

Does anyone have a suggestion?
