Creative exercises for writers

Came across a book by Keri Smith called Mess,Penguin Books

Liked the following suggestions:

1. Find a magazine with lots of pictures, turn to page 32, choose a picture and make a connectin. I'd add to that, write about the connection in 200 words or less.
2. Write with your feet.  And yes you might need a large piece of paper and yes it might get messy but that's the whole purpose.
3. Create a series of chance words then combine them to make a new word.
