Anyone like to help design a play gym?

[Freespin]

As the title suggests =D Over Christmas my partner and i are going to collect some branches etc and build a play gym for my boys. I would love some input and help to design it! Pics are very welcome of what you have seen around or made yourself! I am still trying to figure out where it will fit in my tiny little house but im sure i will sort something out!! As of yet i am not sure on a size though the bigger the better right? hehe

Woods we have easily available to use include the following
Manuka
Feijoa
Bamboo
Radiata pine ( aka my christmas tree haha)
We also have a huge amount of Macrocarpa around (shelter belts) but i cant seem to find anything much to say if it is safe or not?? Can anyone help there?

Would love it if anyone wanted to draw up a few draft ideas for me =D
