What's This?

Walking in front of the Dela Warr Pavilion we happened upon this construction. I immediately thought they'd knocked up a bit of a kiddies' playground - but no, it's the DLWP's latest art installation, entitled, 'Invertebrate.' Well I have to say, that I don't geddit, me being an uncultured one, but even Gill, the art lover, indulged in a spot of head scratching! :-)
