Constraints as a design principle: the DARPA Heavy Lift Challenge
I love competitions where constraints are one of the principles. I used to participate in size coding challenges where you had to deliver a graphics animation in a few KB (4 or 64). It was challenging, you had to learn every single detail to get most of it.
There are competitions like this in the real world, one of them is the DARPA Heavy Lift Challenge. If you forget about the final objective, the challenge itself is super interesting. There were super creative solutions but the winners were classic designs like a helicopter and a drone.
But it does not mean the process is not interesting. This video from the guys in second place shows the actual painful process to get to the best lift ratio. It looks easy but you see how every small detail is important when you stress the system.
