pulled apart a few broken cell phones in the last few days one being an iphone, just wanted everyone to know that there are a bunch of plastic films on the display that make all kinds of great effects with lasers.

Thanks for the info. Old, broken, phones of all types have bunches of great little parts that you can use for different experiments ie, the little motor inside that's used for the 'VIBRATE' feature, makes a great little motor for a mini-spiro. There are also LED lights, & some phones have a nice rubber pad that has molded buttons on it for the key pad. You can cut each one out & keep them in case you ever need a replacement button for a 'PEN STYLE' laser. All kinds of goodies are in there. rob
