YouTube recommended this video quite a few weeks ago to me. Saw it from start to finish (don't do this quite often). I immediately got the thought how great it would be if this genius would proof his interest and talent in the digital counterpart and within the PC Editor community, creating new locomotives in the same way as for his cats. He already is very akin and professional with 3D modelling. Also he kind of knows a bit about programming (is that Arduino?), so the step to the PC Editor and Unreal Engine wouldn't be too far. Have fun. Cat Sized Lego Train by BrickTechnology
