hahaha.. No need, the natural / original rocks are easily available here, the mini temple from stone also available. I use statue because I want something different. Maybe one day will make something like this, but the price of the kungfu statue is too expensive.
Surprisingly the video showed some bonsai expert showing the process of making the rocks, I thought the bonsai people will like everything natural, not manmade.
I ever made a pot from rock, with minimal tools available, this is solid, not the one in the video that is very soft..
