Came up with a sign for the Truck for when it is at an event. Wanted something that told what it was about at a casual glance, and not be put off by too much information. The QR codes I created goes to the website of the build and the YouTube playlist on it if people want to know more.
Had it printed on some aluminium composite material so will last a while. Was able to use my wife's experience in making scientific posters for doing the layout for me.
