Visual imp, you are aware that the thing that lights the apple on the back of the display is the backlight of the LCD. The only way to change the color is to use transparent red films/gels.
In hindsight, after my long ago previous post in this thread, I stand corrected. Its actually prettty easy to do this, assuming you have the supplies. If you carefully pry off the front bezel, you'll see a seried of small philips head screws all around the left, top, and right of the display. remove them. You dont have to remove the small ones near the isight. Pry the display away from the bottom, rather than the top, and slide it downward. it'll come right out. On the back of the housing, you'll see some LCD buffer pads. the big center one needs to be removed. I start by separating it with a flat single edge razor blade, then pull it off carefully. Set it aside, you want to put it back. Once you've removed it, you'll see your apple logo.
Notice that its white, unlike the old ibooks. Its also held in place with adhesive like always. I've found that by pressing on the outside of the display with moderate force, you can get the adhesive to let go, and you can pop it out. Now you have to get that white paint off.
Just so its said, this isnt the same white paint as ibooks and such. Alcohol wont remove it. you have to sand. Go to your auto parts store, and get some 2000 grit sandpaper. Get a polishing cloth, and some 3M rubbing compound. Then head back home to the sink. Soak the sandpaper, and soak the apple logo. put the paper on a flat surface, and put the apple logo on the paper. begin sanding in a curcular motion. Move the logo on the paper, not the other way round. The flat surface will help you sand evenly. As you go, you'll see white particles build up in the water on the paper. Rinse things off regularly to get rid of the removed paint particles. You'll see the apple start to clear up. Once its clear, dry it off and check it. it should have a haze to it. If its uneven, keep sanding. You want a light, uniform swirl pattern. Once you're there, break out the rubbing compound. You dont need a lot. A pea sized amount will suffice. put it on your polishing cloth, and start polishing. work in a circular manner periodically, wipe away the excess, and look at what you've got. When its crystal clear, you're done.
Pop the Apple logo back in and you're ready for the next step. I use 3M Multi-purpose inkjet/laser transparency film for my substrate. Any office supply should sell it. Work out your art in photoshop, gimp, whatever, and print it to the film. Test print a couple times, to make sure you've got it nailed. Then, stick the film over the Apple. I usually put it in place with simple scotch tape. Re-apply the display padding with scotch tape around the edges, put everything back together, and you're done!
If anyone's interested, I have the .jpeg I created for the rainbow apple I've been doing for all my coworkers. Let me know and I'll pass it around.

Okay, so here's the image I created in CS3. its a pretty simple .gif file thats 2.5 x 2.0 at 72 dpi. Granted, I was working at 300 dpi, but thats me. If anyone wants a larger file, I'll re-export it, zip it and post a DL link to it, hosted on MYM.com

I do have one question, though. Does modding my monitor like this void the warranty? I'd think it would considering I am using a screwdriver to do this.
