I made a thing, It shows the number of people waiting in the Monzo customer care queue and looks like this.

Animated gif of led strip lighting up.

Inside it uses a raspberry PI running python mechanize and pyserial, talking to an arduino (cheap clones for the win.). All the animation is done in the arduino, the rapberry just sends 1 byte. (A for 0, up to x for 58 waiting).

Close up of the thing, showing about 30 people waiting in our queue.
One clap, two clap, three clap, forty?

By clapping more or less, you can signal to us which stories really stand out.
