In town a few days ago, I saw that Trinity Street had come to a standstill, watching a young woman placing hundreds of origami boats (she had in fact made exactly 1000) in a neat line along the kerb.
I stopped to ask her what it was all about, and she told me that she was a Fine Art student at Anglia Ruskin and this was part of her final year project. The boats were spilling out of a small gallery on Trinity Street, and was apparently a comment on whether art should be confined to galleries at all.
She also told me she had plans to set the boats free to float down the Cam when the exhibition is finished. I had my reservations about this, especially as this was just before the Great Cam Clean Up, but she assured me she had permission!
