Next time you go and decorate the tree, put a heel lift in your left shoe!

So you picked up on the fact that right side is supposed to be higher than left, like a string of lights spiraling up the tree.
Pretty good eye.
BTW I am hoping @dbox will catch this on one of 3 forums and figure out what I am missing for QBJS.

Yep, better than the average Cyclops. I'm sure db will see it, and tree it.

In some places and cultures, the left side is wicked. So raising the right side is considered a normal thing and "good luck". Being left-handed was horrible in a society that condemned the left side.
"AARGH I killed it! Everything I touch gets ruined." This line from Charlie Brown almost made me cry.

Except the "blind" side of the tree is going to have less lights for that picture. Maybe a bit more separation between the lines that could be seen could be more realistic.

Gee Thanks. I ran your program before sunrise, and a plane crashed into my house! On the "bright" side, I really think these onboard peanuts are underrated.
250-something was my favorite.
+ 1 on the finished spiral design, too.
