SURVEY: What is the best thing made in GH that you've ever seen? (Animations included)

What spontaneously comes to mind is @AndersDeleuran’s amazing, animated car parking simulation, as well as pretty much all of Antoine Maes’ freakishly beautiful and smooth motion graphics.
If you’re interested, you can also take a look at some of my humble projects, like my 4d cube or my take on the travelling salesman problem.
