I was recently made aware of Lidpop.

Lidpop is a nifty piece of utility software for your Mac. There’s no reason to have this app other than it’s fun. Too often we purchase apps or software for our Macs and expect them to do a great deal, and then we get annoyed when they don’t.

Lidpop allows you to add some personality to your computer by playing sounds when it sleeps or wakes up. Whether you want your machine to wake up with a rooster call, or send it to sleep with a sliding whistle, the choice is yours.

You can choose to have Lidpop start automatically at startup, and it’s got a nice minimalistic icon which you can select to appear in your menu bar.

I would have liked more sounds to choose from, but for $1.99 I got more than my fair share of laughs and giggles.
