So here it is! This is how the unit looks without a flashcard in it. The cards are stored in the back.  Once a card is inserted (and provided there is a MicroSD with a language pack in the device too), it's play time!  Here is a little demonstration of a fully operational unit , switching flashcards. While these particular prints look pretty cool, I must stress that the unit can read flashcards printed with a regular home or office printer as well.

And for your bloopers section, this is what happens when you scramble the file names.
