On a side note, if your fan started spinning up when you opened this, it's because of the particle simulation in the header.

I know because I reviewed this library (https://github.com/VincentGarreau/particles.js) when a colleague wanted to add something similar to our site. The problem is it uses a naive O(n^2) algorithm for linking up particles when they get near each other, which wastes a lot of CPU cycles.

Running this script with a large number of particles and auto-linking on is ill-advised - but fortunately you can delete the <canvas> element quite easily to stop the script.
