Marble Madness is hands-down one of my favorite arcade games of all time. That said, I really stunk at it. Rolling Madness is a clone of Marble Madness, done using OpenGL and other open source tools... It looks great, and plays perfectly. Unfortunately, I'm just as bad at this as I was the original. The author appears to have used the same music and sounds from the original game, which I hope doesn't cause any trouble, because this one really takes me back. I can almost hear that pocketful of quarters jingling. One of the neat features in Rolling Madness is that you can switch from a true perspective (possible with today's machines), as you see in the screenshot here, or you can use the old perspective from the original, which was really an isometric view. Either way, hours of frustrating ball rolling is yours to be had. I tried using the keyboard controls, but the mouse is a nice change of pace. This has definitely secured a spot in my MAME cabinet (which does not yet exist). The only negative I can find is that it's Windows only. Thanks to David for sending this in!
