Did you ever wish your desktop looked like Super Mario Bros.?
No?
Oh. Sorry for wasting your time then. Move on.

This config accurately replicates the heading information you'd find in Super Mario Bros. for the NES with your own info. In my config, I have replaced Mario's name with the computer name, and the score with the uptime in minutes (times 100). The 'coin' count (which is animated) shows the current percentage of free memory. Instead of seeing a 'world' number, the date is shown next. Lastly, the time is replaced with the real time. Obviously you can change any of these, this is more of a guideline.
To use: Place the coin.gif image in the /icons folder, move the script into the /configs folder and edit the filename of the coin image, and install the font that is included. Optionally, use the background included to make it really look nice. The background and config are optimized for 1024 x 768 (because that's the res. of my secondary monitor), but a little photoshopping and a couple of minutes can fix that.

If I get a good response, I'll work out some other popular games (SMB3? Zelda? Who knows...)
Enjoy.
