It would be cool if the people who participated in the 72 hour contest could also make a reply about their experiments (if they tried any) in this thread:

Not necessarily now, maybe it might be better to play the maps more through to the end so we really know how they worked out, but sometime.
Paraphrasing Elon Musk from
here; it's important that people try things that are different and more importantly better, but also it's important to create an environment where that sort of thinking is encouraged, and also one where failure is okay. In a lot of cases trying something new will fail, but if every time someone came up with a new map idea it had to be successful then people won't want to come up with new ideas.
