Yoko Ono has created the *Peace Tower* to honor John Lennon.
On her website, you will also find her downloadable billboards.
The free download of Yoko’s Times Square New York City billboard of the famous phrase *Imagine Peace* in 24 languages is available in several sizes–HERE.
Yoko Ono has also been creating Wish Trees.
When I visited a temple in Tokyo with a Japanese friend, he showed me long strips of paper printed with wishes, that visitors tied to trees or bushes— a common practice at temples in Japan.
Yoko Ono has made her Wish Tree project instructions available for download here.
