This is an awesome, super simple site (with horrible look-and-feel) for making your own ringtones from audio files. Someone posted this on Tumblr recently; sorry for no attribution, but I don’t remember whom.

I just made a few ringtones from Max Richter’s 24 Postcards in Full Colour — a goal of mine long-thwarted by Apple. Richter ringtones are finally mine, bitches!
