I have just finished the website for my "Teachers Timer" project. This is all based on the documentation produced for the Circuit cellar competition last year.
here is the blurb:
Teachers Timer is an innovative and discrete timing device for assisting teachers and lecturers. Using cell phone style vibrations and a simple one-button interface the user can be alerted to the passage of time without staring at the clock. For lectures and presentations the device can also include a laser pointer that will gently fade in and out to alert the user.
My station master project is also up at brokentoaster.com/stationmaster/
