If you have an LCD with a giant crack running through it, make a mirror instead of throwing it away. The crack is nearly invisible after the operation, see picture.
This is really easy, and just amounts to tearing apart your screen, flipping over the reflective part, and putting it back together.
Actually, the biggest challenge was being a little creative about hanging it.
You'll need a little computer screwdriver and some scissors, plus whatever you plan to use to hang it. I'll leave the hanging to your own devices.
Step 1: Disassemble
Ok, ripping apart. Take your little screw driver and just take it all apart. I saved a small piece of metal to use to hang the mirror. Most of the frame can go away.
The big white strip (green on the other side, pictured) that says "do not touch" should be cut off with scissors.
