A filtered view

or is it 'a filter view?' We have had some problems with our air-warmth-collector. It is collecting also other things than warmth, like stink, water and bugs. We are currently in the process of complaining to the right instances. This picture is before cleaning.

I realised after posting the Blip that this concluded the year of Blipping. It went fast. Really fast. Thank you all for comments! And please do keep commenting!!
