Here are some cool ones I put on my board:

Background Image

Tag: bgimg

Replacement:
<table border="0" style="background-image:url({option}); background-position:top; background-repeat:no-repeat;"><tr><td>{param}</td></tr></table>

Example: [bgimg=urltoimage]Message[/bgimg]

Puts an image in the background of the text.


Border

Tag: border

Replacement:
<table border="0" style="border-color:#7282A9; border-width:thick; border-style:{option}; padding:0;"><tr><td valign="middle">{param}</td></tr></table>

Example: [border=outset]Message[/border]

Puts a border around the message. Options: dotted, dashed, solid, double, groove, ridge, inset, outset

Hover

Tag: hover

Replacement:
<span onmouseover="this.innerHTML='{option}'" onmouseout="this.innerHTML='{param}'">{param}</span>

Example: [hover=Hovering]Hover[/hover]

Changes the text when you hover the mouse over it.

Click

Tag: click

Replacement:
<span onclick="this.innerHTML='{option}'" onmouseout="this.innerHTML='{param}'">{param}</span>

Example: [click=Clicked]Click[/click]

Changes the text when you click it.

Hold

Tag: hold

Replacement:
<span onmousedown="this.innerHTML='{option}'" onmouseup="this.innerHTML='{param}'">{param}</span>

Example: [hold=Holding]Hold[/hold]

Changes the text when you click and hold down on it.

Hide

Tag: hide

Replacement:
<!--{param}-->

Example: [hide]Hide[/hide]

Hides the text so it can only be seen when editing the post. (Good for leaving comments in posts that various admins/mods will be editing.)



Also, for Blink, you can just use

<blink>{param}</blink>

. It doesn't work on IE, but neither does your method.
