After dark...

I don't claim that this is a great shot, but the subject is quirky and mysterious. A shop window in Fisher Street, Lewes, where the glass is whited out while renovations are made. But a letterbox shaped gap in the whiting reveals a troupe of little animals, and part of a weightlifting rig (left of picture)...

What's this all about? Does anyone know?

Ps.... by the way, the light comes from an anglepoise in the shop, aimed at the display. The shot was taken without flash...
