On my kitchen window

Ok it may border on the edge of pornography but I swear this is no set up.
Noticed this accidental "still life" on our kitchen window today.

For some reason which I am still not certain of M found it necessary to bring a chunk of the car (well, windscreen wiper) into the kitchen to have something glued on to it.
And it so happened he put it on to a section of the Guardian G2.
The rest?...well I leave it to your imagination.

Why the batteries? Well, they are part of my sound outdoor installation tomorrow night at the Smith gallery, all part of the Creative Stirling First Friday pop up art events.
