Over at the MathWorks discussion forums this month, some of us have been <\/span>vibe coding MATLAB Christmas trees<\/span><\/a> using various AI models. One of my favorites came from <\/span>Vasilis Bellos<\/span><\/a> who worked with Claude Opus 4.5 to enhance his <\/span>code from last year<\/span><\/a> which was based on the original Rotating Christmas Tree code from <\/span>@Zhaoxu Liu \/ slandarer<\/span><\/a>). The <\/span>code is available on the forum post<\/span><\/a> and the result is shown below. A great collaboration between human and AI programmers.<\/span><\/div>

MathWorks' own Hans Scharler took this in a different direction by vibe coding an entire application that allows you to design a Christmas tree and then generate the MATLAB code to reproduce it! While taking the screenshot for this post, I noticed a little glitch with one of the sliders on my Mac. I am sure that Hans (or his AI agent) will soon update the <\/span>application's GitHub repo to fix this<\/span><\/a>. Download it and have a play or just open it in MATLAB Online by clicking on the badge: <\/span>\"\"<\/img><\/a><\/div>

There are a bunch of other examples in <\/span>the forum post <\/span><\/a>from various members of the community and I encourage you to go take a look. It will be interesting to see what we can do with AI next year!<\/span><\/div>

A MATLAB tree from Christmas past<\/span><\/h2>
The work shown in the forum post is a continuation of a long tradition where members of the MathWorks community have been using MATLAB and Simulink to produce holiday-related artwork. 20 years ago, Michelle Hirsch highlighted this example on the <\/span>Pick Of The Week<\/span><\/a> blog.<\/span><\/div>

Written by community member, <\/span>Marc L\u00e4tzel<\/span><\/a>, the 20 year old <\/span>code is available on File Exchange<\/span><\/a> and still runs flawlessly today<\/span><\/div>

An unreal Christmas tree in Simulink 3D Animation<\/span><\/h2>
One of the more recent Christmas tree related submissions is this <\/span>Christmas tree in unreal engine<\/span><\/a> by community member, <\/span>halleyhit<\/span><\/a>. This makes use of <\/span>Simulink 3D Animation<\/span><\/a> to render a Christmas tree in 3D using Unreal Engine from Epic Games.<\/span><\/div>
