While hunting for a way to access the service menu on my Casio Exilim EX-S500 pocket camera, I found a wheel of fortune function.

With the camera turned off, hold down [left], and press [Play] (the little arrow in a square), and the camera will randomly flip through all the images on the screen going bip, bip, biiip, biiiip, slower and slower until it stops, displays a random photo and goes “swuuuush”. I’m not sure how drunk you have to be for that to be useful…

I never found the service menu.
