1 empty CD case (you'll get 2 chimes from each case)
Access to a Laser Cutter (I did mine at TechShop Pittsburgh. For information on TechShop and to see if there is one in your area go to www.techshop.ws)
Some shiny baubles
Step 1: STEP 1 – DISASSEMBLE CASE
When placing the case onto the cutting bed set it with the solid piece raised, not on the surface. I tried it the other way and when the laser moved it pushed the edge of the case moving it out of place.
