Look at this image:
It was created by a 73-year old Japanese artist called Tatsuo Horiuchi. On Excel. Yes. Excel. The world's major spreadsheet application used for making numbers work. Not the thing for making beautiful imagery.
Horiuchi says he struck upon the idea of creating art with Excel after his retirement after he watched some of his colleagues creating graphs with the applications.
The thing I love about this is how it shows that where the will to create pushes it can break through any barrier like a little sapling reaching up through a concrete slab.
