2020年的夏天，關恆在翻牆後閱讀到美國媒體BuzzFeed News關於新疆再教育營的報導後，在疫情期間受到其他中國公民記者的啟發，故希望能到實地拍攝及記錄，除了見證歷史，亦能訴說一個與官方版本不同的「再教育營」敍事。
Even the simplest rewrite rule—say, replacing a deprecated message with a new one—usually sends me hunting for examples. During this project I spent a lot of time deep inside the rewrite engine, and even now I cannot reliably recall the exact syntax.

While there exist many possible ways to triangulate a set of points, the most common method for TINs is the Delaunay triangulation. This is because Delaunay triangulations tend to produce more regular tessellations that are better suited to interpolation. In theory, we can represent our colour palette as a TIN by computing the 3D Delaunay triangulation of the colours in colour space. The nice thing about this is that it makes finding an enclosing simplex much faster; the candidate selection process is simply a matter of determining the enclosing tetrahedron of an input point within the network using a walking algorithm, and taking the barycentric coordinates as the weights.
