Volteo de letras

Aquí les dejo un code muy simple para girar las letras 180º, que hice cuando intente aprender javascrit xD.

Les dejo el source y un demo en mi ftp personal para que lo vean

<script>
function flip() {
var result = flipString(document.f.original.value.toLowerCase());
document.f.flipped.value = result;
}

function flipString(aString) {
var last = aString.length - 1;
//Using arrays
var result = new Array(aString.length)
for (var i = last; i >= 0; --i) {
var c = aString.charAt(i)
var r = flipTable[c]
result[last - i] = r ? r : c
}
return result.join('')
}
//Here I turn 180º de letters
var flipTable = {
a : '\u0250',

h : '\u0265',
