Modem speed simulation in Javascript

I had to program something that simulates a slow internet connection today and that got me thinking that it would be nice to show textfiles files with a simulated modem speed. The page is pretty simple, the text file is converted to a Javascript string and is being displayed in a span with a simulated modem speed. I have created two files from the top 100 list, ad.txt is running at 300 baud, adventur.txt is running at 1200 baud.

The cursor animation and tty stylesheet is from this page https://gist.github.com/navinpai/2902229

The files are from http://textfiles.com/100/ by Jason Scott, I assume the files are free to use.
