Thanks for the reply! I did a little searching the forums and found that it's been down for a couple of weeks now. It's a fun project for a semi-beginner like me, and I'm looking forward to it coming back. I bought everything but the lights in anticipation of cutting my own acrylic and putting it into an old portable TV I salvaged.
I don't want Adafruit to put out a project tutorial it isn't confident about, but I'm excited to make pretty lights.
