Having spent a bit of time with playing with both Blender physics and drivers, I started to think about combining all the elements into a short sequence. I wanted to create a character and an animation that combined all the elements I'd been looking at - I designed the initial character in LDCad and then imported it into Blender.
I knew how important the eyes were going to be, so I used three different circular round eye tiles that I planed to animate between in Blender, to create a blink (there are other tools available for animating minifigure rigs and expressions in Blender including EpicFigRig https://github.com/BlenderBricks/EpicFigRig) - but I wanted to keep it simple!
