2017-01-18 visualizing website hits with a LED ring
I was always curious from what part of the world the visitors of my websites (vanheusden.com, www.aliensdetected.com and www.slimwinnen.nl) are coming. For that I created this thing (see photo below). It shows (using GeoIP) from which country a visitor is visiting. The place on the circle is selected by longitude and the color by latitude (the latitude is mapped to the H(ue) component of the HLS color scheme). New visitors trigger the fading away of previous visitors.
