At my first job (which was a startup) they did this thing after you worked there for 90 days. They would get everyone together and make a big deal about the new person and their role in the company. Then, they would give you these set of cubes.
I also remember that everyone had kept these cubes on their desk at that company. It was a cool thing that was part of their culture.
I still have mine. They are a bit scratched up as you can tell from this photo I took the other day.
But I keep them around because they remind me about the upside of rejection.
