So I saw the video @ https://www.youtube.com/watch?v=6GEpqmPL3bg - so full credit to this guy, but I felt the need to give it a try. I managed to build it in 15:28, which was nice. Also, the main part of the code is only 37 lines long. Feel free to commit better versions
It is a very simplified version, but it still does what the TSA's $1.4m App does and for a slither of the price
