Screen lighting up?

Is there any way of making the screen light up when I get a text message? I oftentimes keep my phone on silent on my desk at work, but would like the screen to light up and show me there's a new text instead of just the notification light. Does anybody know a way of doing this?

I'm using a regular Droid.

 

Thanks, Handcent does exactly what I wanted. Now to remember how to turn off the stock messaging app.

 

Sweet, thanks a lot guys! I really appreciate the help.
