New Year's day walk.

The four of us met up late morning. Heading for the beach seemed like a good idea until we got to the front and were nearly lifted off our feet by the 'breeze'. We persisted though and it was OK. 
The beach was littered with litter all in primary colours: leftovers from midnight fireworks. 
This picture was taken along Madeira Drive by Kemptown. We stood and stared at this object, couldn't work out what it was, enjoyed speculating though. Outsider Art? Punks' kids' playground? I wanted to go up close and investigate more thoroughly but was in a minority. Still nooo idea what we were looking at.
Any thoughts?
