Maelstrom is a shareware Asteroids clone for the Macintosh. The game was specifically designed so that add-on's (i. e., substitute sounds and sprites) could be easily implemented.
Enter Wire. These sounds were taken from several versions of "Ambitious". The idea is that, as the game is played, a dynamic mix of the song is created. Cool, huh?
For more details, check out Ambrosia Software, their page for Maelstrom, and their list of add-on's. The Wire add-on should be on this list in the near future.
In the meantime, it can be downloaded from here:

It's beginning, to, and back again.
