I've just found the gallery that shows all the post cards that were altered by artisits in response to a call by "Serendipity" last year.
I found it a fun thing to do, getting a postcard and having to alter it in some way.
What is more fun is to see what other people did to the same card - creativity does leap off in all directions (fortunately!)
Here's mine just to remind you
