Instruction : "Here is a ray tracing program written in OCaml. Take it and run it by building your own CPU on a FPGA, writing your OS on it and building a OCaml interpreter to run the ray tracer."
Tokyo Japan University students are given this exercise every year. The whole class divided into 4 groups of 4-5 persons each.
They finish it in 4 months.
It's not that one worked, and five people watched him work which is the convention in BD. The 5 person team broke up into 1 or 2 separate teams to design the CPU, write the OS and write the raytracer in parallel. No "I take team work credit because I acted as the cheerleader in the team." And then put in CV "I built an OS".
Follows one adventure story.
