If you don't know EventRecorderMorph and HandMorphForReplay (which I didn't and started to re-implement), they are super cool.

Installation

Gofer it 
    smalltalkhubUser: 'PharoExtras' project: 'EventRecorder'; 
    package: 'EventRecorder'; 
    load.

Example

1. DoIt: EventRecorderMorph new openInWorld
2. Click "record" in the GUI
3. Perform some UI actions
4. Click "play" in the GUI

Your keyboard and mouse actions will be replayed in the World! I know right?! Amazing. This could be really cool for live documentation and executable screencasts :)
