Here I am looking into cogs and mechanisms to see how they work and interact. I am trying to get a range of small to big mechanisms to see how simply or complex I can go. Although with mine I may have a little backstage magic going on but with some key parts and close I will have to have working like it should do to keep it looking real(ish)... and appealing. I have also been looking at how cogs and the machines have been made to help my understanding.
More of an explanation to the one above. I also like this for the noise of the machine.
