Troglodytes

While Anne and Peter and Andy went to Oradour, we went to see some troglodyte farms. Despite their short stature, the two in picture are NOT troglodytes!

They were short, though.

Susie and Cathyt were undeterred by the low ceilings.

Apparently this device was used to restrain children. A bit like a cross between a playpen and a walking frame, the child was put in the square frame, and was allowed to walk roound and round the central pole. No mention of electricity generation, but I think they missed a chance there.
