Made this lamp for my family for christmas. Stands at about 5 feet tall, 10 lights on each side of the central pillar – 40 lights in total.
The code is just a modification of Mark’s Noise demo code, however I created all the palettes myself and slotted them into the timer that was available. I set each of the 20 palettes at 3 minutes each, then cycling over from the beginning after an hour. Thanks Mark! My family loves it 
Here’s a copy of the code, feel free to use any of the color palettes I created (including a candy cane one!)

And here’s a demo video, which blasts through each palette at 10 seconds each:
