Presentation Timer Pro description

Presentation Timer Pro is a presentation timer that provides configurable color cues at different points in your presentation to help you stay on-pace.

Presentation Timer Pro supports presentations up to 100 hours in length. Checkpoints may be specified at arbitrary times throughout your presentation to help you to mark time. At each checkpoint, the timer may be changed to an arbitrary color of your choosing. Additionally, the application can be configured to optionally beep and/or vibrate at each checkpoint to provide auditory and tactile feedback as time passes.

This application is both "free as in freedom" and "free as in beer". If you'd like to tinker with its source, it is publicly available here:
