I came across this really neat ad on PPP for a website that lets you create avatars with custom "ringtones" for your cell phone. You can check it out here. You customize the avatar to look like yourself or whatever you want, and then either record your ringtone, pick a pre-recorded one, or type what you want it to say and it converts text to speech.

You then download the avatar tones to your cell phone, email them to your friends, and publish them on your MySpace page.
