fkeel,
We completed the nebula project a couple of nights ago and yesterday my 11-year-old son showed it to his class. No grade yet, but my guess is he'll get an A. Certainly the kids and the teacher gasped when he pushed the button. Thanks so much for the help. Here's a YouTube video of it as promised:
Thanks again for all the help. He was so happy with it and jumpstarted his interest in learning the code. We're actually thinking we'll make a larger one to put in the fireplace. Much cooler than a fire!
