Marianna has the special LEDs I brought in for you guys, check with her to get some! If you need more switches or batteries, you can check out your local Radio Shack or order LEDs from SuperBrightLEDs.com, Adafruit, or elsewhere online. Order early if you are having anything shipped, so you have time to work and play with your materials!
