Undrawing a Portrait

This digital creation is a tiny little 'app'. Unzip the file, go into the resulting folder, open 'index.html' in your browser and then endlessly scroll up and down - drawing and 'undrawing' the portrait. Fun.

With this work, I am trying to show that some art can only exist in the digital realm. The danger of this? How long will the technology be around to support the piece? Art can truly become 'obsolete'.
