At the Mesh conference I met Dave Hyndman who later posted a tweet (a message to Twitter) sharing this video with everyone. It really is mind-blowing: animation created on public walls. The scope of this project is incredible. [Note: for full effect hit the full screen toggle (the four arrows pointing outwards) to view video.]
MUTO a wall-painted animation by BLU from blu on Vimeo.
When you have finished watching this, I encourage you to explore the artist BLU's website also, since it is a fresh take on websites, too.
How can we do for librarianship what BLU is doing for animation? How can we "take it to the streets" and do something so simple but yet will blow people's minds?
