I have a huge collection of polystyrene pizza trays that I have used in the past to make shrinky dinks. I aim to recycle one tray a day into approx. 8 swallows each time, that together will hang, on thin wire, to make an installation that references issues of migration. That could be 800 swallows! (update: Day 22. Swallows have morphed into housemartins and now that shrink ratio has been established...my huge colection is 38 trays, approx 4 housemartins per day...that's 152 birds....still enough to be effective!)
Of course perhaps it is not swallows but HOUSE MARTINS that I am making! That ties in better with the 'refugee' 'imigration' ideas! The installation will be about housemartins, not swallows. They are easier to cut out and much more black and white too!
No housemartins here either this year, but we get fly pasts now and again!
