This user macro allows you to add a typewriter text effect to your content, adding one letter at a time until the text is fully displayed...

Installation
Go in to your Administration panel, choose "User Macros", then add a new user macro called "typewriter" (or anything else for that matter).
Make sure you tick "Macro has body".
Paste the following code in to the text area:
#if ($action.isPrintableVersion())
$body
#else
<script type="text/javascript">
var text = String("$body").split("");
var tid = 0;
if (document.typewriters==null) {
document.typewriters = [text];
document.doTypewriter = function() {
var x,c,s;
var more = false;
x = document.typewriters.length;
while (-1<--x) {
s = document.getElementById("typewriter"+x);
c = document.typewriters[x].shift();
if (c!=null) {
more = true;
s.innerHTML = s.innerHTML+c;
}
}
if (more==true) {
setTimeout("document.doTypewriter()",200);
}
}
setTimeout("document.doTypewriter()",2000);
} else {
tid = document.typewriters.length;
document.typewriters.push(text);
}
document.write('<span id="'+"typewriter"+tid+'" />');
</script>
#end
Poke the "Add" button with your mouse and you're ready to go!

Example of use
Throw this in to one of your pages:
{typewriter}Well, this is my simple typewriter user macro, notice the dot moving along after this text{typewriter}.
Hyperlink: [{typewriter}Although it won't work handle wiki text, you can at least wrap wiki text around it such as this link{typewriter}|Plugin Index]
You can also {typewriter}use it to insert text in to existing text{typewriter} if desired?
{color:red}{typewriter}You can change the colour and plenty of other things by wrapping other macros around it.{typewriter}{color}
Save the page and sit back and watch!
I also took the time to make it instantly display the text when in printable view (you don't want to print a page that's mid way through a typewriter effect do you?)
Wishlist
There seems to be no way that a User Macro can find out if it's already been used on a page - as such I had to output the doTypewriter method each time it gets used, and to try and make up for this shortfall I only actuall attach it to document if it's not already there.
Being remarkably lazy, I set a 2 second (2000 milliseconds) trigger to start the typewriter effect. Obviously, if you page takes more than 2 seconds to load and has loads of uses of this macro, things could start going pyriform. If your page loads really quick, then you will be waiting for 2 seconds before anything happens!
Feel free to dive in and improve this script, it's just a little plaything and I'd be interested to see what improvements can be made
