Some Great GBC Modules by akiyuky

I am a big fan of GBC modules, just because so many of them require some creative thinking, but a couple of these by YouTube member akiyuky have some cool mechanical features...

This one is particularly impressive because it has several well choreographed movements using only a single air source.




This guy does a nice job illustrating how water was pumped by the ancients.
