The May 2008 edition of Popular Science features a simplistic game built with a device called a ScreenKey. A ScreenKey is a small LCD screen built on top of a button. There is even a microcontroller kit. Could be useful for purpose built interfaces… 

It is strange what a Google search for “Semiconductor Physics” returns these days: Britney Spears’ Guide to Semiconductor Physics. I am trying to get back into electronics after 12 years away and I am sure using a pic of Britney to help demonstrate the Conduction and Valence bands will have me back on track in no time at all. I would learn faster if the site featured Madonna but I guess thats a site a Madonna fan, such as myself should create.
