Entry 11: X-MAS tree with DYNAMOIMBU words
I thought of a random arrangement of words placed on a tree. And I tried to find an arrangement of words that matched like a bingo game in the order of the words D, Y, N, A, M, and O.

Hello Dynamites!
We are super excited to bring back a very fun series - Dynamo Challenges is here again! It is meant to inspire, to push you to think out of the box, to grow your knowledge of Dynamo and more than anything learn from each other and have some fun together! 
01 – Christmas Ornaments Challenge: The first challenge is meant to be more for fun and to bring in the festive holiday season in and say our goodbyes to 2024. 
It’s that time of the year again, where most of us are setting up our Christmas trees.
Did you ever want to have your own custom designed ornament or tree topper? Well now is your chance!
Come have a go at designing your own Christmas Ornament and share it with the community. For those of you who don’t celebrate Christmas, bring out your ornamental fun across a category of your choosing! Maybe something to hang at your front door window or something to decorate your matlepiece or a custom desk toy to add some fun to your desk. It could be anything and all flavors of ornaments are eligible! 
This challenge might also be a good way for you to explore the Panel Nodes, T-Spline nodes or the new OOTB Mesh Toolkit nodes.
This challenge will run for 2.5 weeks, starting on Wednesday November 27th at 9am EST, running until Monday December 16th at 5pm EST.
ENTRY REQUIREMENTS:
- Dynamo must be used in or part of your submission.
- If you use a Dynamo graph, your .DYN file must be attached to your submission.
- If you use a Custom Package or Node in your submission, it must be hosted on Package Manager. Note: This may mean uploading a package!
- This topic will be left open for discussion - use to your hearts content! Upon deadline of challenge, moderators will edit the post to introduce a community poll to select winners.
- We very much encourage wrong answers! Just have fun with it!
SUBMISSION OF ENTRY:
All submissions are blind via Direct Message to @solamour, @achintya_bhat , @emrullah.yildiz and @jacob.small with the Challenge as your title - this link will start a handy message template. 
Please include all relevant files to execute the graph and reproduce your result as well as a still image(s). 
PRIZES:
- 1st Place = “Dynamo Challenge Winner” forum badge
- 2nd Place = “Dynamo Challenge Runner-up” forum badge
We are super excited to see what all of you come up with this time! We have more challenges lined up for 2025, we will share the line-up with you all in the new year.

wow! These are epic!
But you didn’t include the one I posted earlier in this thread. It’s already got 17 votes.
How long do we have to vote?
EDIT… oh it says two weeks… I can read… honest
@Alien There is no competition when compared to the one you posted on the thread. It is already a winner. So, left it out to give everyone a fair chance to win

thats awesome @solamour, what’s your preferred method for spirals ?
I guess Sol have used a helix ootb…but not sure…but a really nice tree/ornament
I think the Helix nodes have a constant radius I was wondering if there was anything more elegant or OOTB than than below, to get the spiral to move towards the centre?
circle = 5*360;
z_pts = Point.ByCoordinates(50,0,(0..50..#circle));
angle = 0..circle..#(circle+1);
zx_pts = Geometry.Translate(z_pts, Vector.XAxis(), 10*Math.Cos(angle));
zxy_pts= Geometry.Translate(zx_pts, Vector.YAxis(), 10*Math.Sin(angle));
nc = NurbsCurve.ByPoints(zxy_pts);
s_pts = Curve.PointAtParameter(nc, 0..1..#100);
factor_xy = 1..0.1..#100;
set_out = Point.ByCoordinates(50, 0, 0);
plane_xy = Plane.ByOriginNormal(set_out, Vector.ZAxis());
spiral_scaled = Geometry.Scale(s_pts, plane_xy, factor_xy, factor_xy, 1);

great yeah …i would try create 2 helix an outer and inner and then surface these 2 by loft and then intersect that surface with the tree surface and we should have the spiral, if that make sense but not sure is the way here as i have to admit i dont do so much in ornaments or X mas trees )))
thanks @sovitek , I had a go a something less surface based, I’ll take a look at your method too !
pt = Point.ByCoordinates(0, 0, 0);
vza = Vector.ZAxis();
helix_inner = Helix.ByAxis(pt, vza, Point.ByCoordinates(1, 0, 0), 1, 7200);
helix_outer = Helix.ByAxis(pt, vza, Point.ByCoordinates(5, 0, 0), 1, 7200);
pts = (0..1..#500);
pts_in = Curve.PointAtParameter(helix_inner, pts);
pts_out = Curve.PointAtParameter(helix_outer, pts);
line1 = Line.ByStartPointEndPoint(pts_out, pts_in);
pts_spiral = Curve.PointAtParameter(line1, pts);
nc1 = NurbsCurve.ByPoints(pts_spiral);
pts_nc = Curve.PointsAtEqualChordLength(nc1, 500);

Thats great, guess we can do it with a coordinate system as well if i remember right, i think @jacob.small have some exemples of that but just build for stairs but im probably wrong
When’s the voting end?
Yes - I did a Dynamo office hour on spiral stairs. 
I would use a cylindrical coordinate system, where the radius input was a function of the height.
