ASCII Art Star Wars: A New Hope
This has been in my "blog about this" pile for years now.
I'm embarrassed by how much stuff I have on my desktop then. I now keep it under 5 things most of the time.
The three Star Wars icons were hard drives.
You can watch the whole Star Wars: A New Hope as ASCII art two ways:
telnet://towel.blinkenlights.nl or http://www.asciimation.co.nz/.
Simply amazing.
