I would love to present a different example which gets the point across better, because both participles of that verb can be used more or less idiomaticly on the same noun. The verb I am using is fahren.
Das fahrende Mädchen.
As Tohuwawohu pointed out, this is pretty much an active participle. The girl is driving. Actively sitting behind the wheel (or on the saddle in the case of a bicycle).
Das gefahrene Mädchen.
Here, the girl is being driven. Considering the word choice Mädchen, it is likely that she is sitting in the back seat.
Context would further provide what else is happening and why the act of driving/being driven has to be put into a participle.
