I’m not the author, but I'm part of the vvvv community. The video walks you through solving the two parts of the Day 1 challenge in vvvv, a statically typed and compiled visual programming language for .NET with state hot-reload.
Most nodes used are actual C# methods, so C#/.NET developers will find it familiar. The video also shows how vvvv represents loops, branching, collections, generics, and mutable and immutable data types visually.
If you’ve joined the Advent of Code challenge, this example might give you a new perspective on visual programming.
The actual coding starts at about minute 9.
