Treemapolis
Your disks, as a city you can fly through. Treemapolis turns the Windows shell namespace into a 3D treemap: every folder is a slab, every file a building as big as it weighs on disk. It is a technology demo of DirectX 12 driven from C# and .NET NativeAOT, and it is also a genuinely fast disk space explorer.

Could you build this?
Partial Building a custom high-performance DirectX 12 3D rendering engine in C# with .NET NativeAOT that traverses the Windows shell namespace requires non-trivial low-level graphics programming.
What it would actually take: The stack involves C#, TerraFX.Interop.Windows/Vortice for raw DirectX 12 bindings, and Win32 Shell APIs. The hard parts are managing DX12 memory heaps, command lists, pipeline state objects, and frustum culling to render tens of thousands of dynamic 3D building primitives smoothly while asynchronously querying the Windows filesystem.
