You might find this fun

It is just an MVC for a slide player with a syntax directed translation for
specifying user preference choice.  I coded the controller and syntax
directed translation, text size and spacing. My friends Alvaro Monge and
Tom Jewett with students Akash Singe and John Sweet did the color picker.
We all contributed to the design of the color picker.

Have fun, I think it will be worth your time.

PS. LV folks turn reverse video is a little ugly when you use this.
