Light in the dark

So, the nights. Fair drawing in aren't they?

I took this just before 9.00pm tonight. The building is an old church converted into flats and I've always been intrigued by this one up in the old bell tower.

The colours you see are constantly changing which makes it quite striking. I'll be honest though: as interesting as it looks from the outside, on the inside it must be like living in a lava lamp!!
