We like this one a lot. Flickr user rudolf_mittelmann has posted a nice shot of his PowerBook Duo 280c running a custom-built HyperCard stack that controls the train you see zipping past. Classic Macs running classic software to complete atypical tasks make us happy.

For the month of April, the theme for our Rig of the Day will be "Vintage Macs" in honor of Apple's anniversary. If you'd like to see your own rig featured here, simply upload photos into our group Flickr pool. Let's see your vintage Macs (Apples and Newtons, too)! We'll select an image every day to highlight.
