One the problems with the new 2.5 redesign is that there is no way to animate string type custom properties that we might like to associate with our objects.
Re:Phrase is an attempt to add string based animation into the mix.
Pull the BLEND file down and press Play to see it in action.
After you run or install the file addon_re_phrase.py (contained inside the attached BLEND file), press SHIFT-A in a 3D view. Choose RE:Phrase Text Animator to add a managed font object to the scene. You can add multiple RePhrase objects to your scene. Select the RePhrase object and then activate the Object properties context for the object. Scroll to the bottom and you should see a RE:Phrase panel. Use this panel to add multiple phrases to the font object. Click the + or - buttons to manipulate the list. Select the phrase directly to edit it. Animate the Phrases_Index property to change the phrase over time.
