Behind the panel lies the router and modem along with an electrical bar for the space. They would have normally come in at the bottom by the floor (you can see the hidden cord running up the wall), but putting them in a box or basket would have made the footprint of the room seem smaller and weighed down.
Instead, things have been run up the wall and displayed proudly. Plus, when your internet goes down and you have to do the unplug-replug thing, it's easy to see which little lights are on without swearing up a storm. Wait, only I do that? Well carry on then. There's more at Mamamekko.
