The materials and tools you will need:
- needle nose pliers
- super glue
- cheap paintbrush :: make sure that it has a metal bristle handle that has an edge so that you can open it up with the pliers. It needs to be metal because it needs to conduct the electrical charge from your body to the screen thru the conductive thread. The iPad's screen is capacative. You can read more about it different touchscreen technologies here: http://en.wikipedia.org/wiki/Touchscreen
- conductive thread :: I found that Sparkfun's 2 ply ended up having the straightest threads after untwisting / unravelling it.(http://www.sparkfun.com/products/8544)
- patience :: unraveling the thread and putting it back together takes a barrel-load of patience
- iPad with a painting App :: how else are you going to test it and have fun once you are done?
