Today at a train station in the Netherlands (Utrecht) I noticed something special. I saw the letters hjkl on the sign in reverse order. These letters indentify the platform areas where you can enter the train. Depending on the length of the platform and the area where the train has entrances, it shows the letters.
Either this was super coincidence, or someone at the NS (the Dutch train company) is a vim fan and payed tribute to Bram like this.
