C#, (削除) 131 (削除ここまで) bytes

Not much to explain. It just takes a string (wrapped in "") as argument and prints each character using the correct delay pattern. After the animation it exits with an OutOfRangeException because the loop doesn't stop after it looped over all characters. Since it's an infinite loop, that also means I can use int Main instead of void Main ;-)

Golfed

class C{static int Main(string[]a){for(int i=0;){System.Console.Write(a[0][i]);System.Threading.Thread.Sleep(i++%3<1?500:100);}}}

#Ungolfed

class C
{
 static int Main(string[] a)
 {
 for (int i = 0; ;)
 {
 System.Console.Write(a[0][i]);
 System.Threading.Thread.Sleep(i++ % 3 < 1 ? 500 : 100);
 }
 }
}

• Saved 1 byte by moving incrementing i inside of the Sleep() method instead of in the for loop. (Thanks Maliafo)
