Claymation Improvement

claymation movies are great and lots of fun to make but what if you could make them just a little bit better by adding simple emotions with LEDs

different colored LEDs (two of each)
a small 3 volt watch battery
a lump of clay

just make your signature clay figures!

now put the two LEDs through the front of his/her head and the wires will be sticking out the back.
attach the battery to the LEDs and now you have emotion
