I've been trying to develop a portfolio in Flash to show both my artworks and code experiments and this was my first attempt for the main interface
This is done entirely by code, reason why the file only weights 4 kb

I have an empty movie clip that generates the fading and flipping square, depending of which frame is selected
The code in the main stage calculates how many rows and lines of squares are necessary and places them according to the width of the squares and the given interval between them
A matrix is used to determine which squares have been placed and if they have are flipped or not

The reason I gave up on this interface it's because the amount of squares weighted a lot in the processing time and how time consuming it was becoming to ensure no bugs occurred (the color changing of the buttons is one, but I've kept it on purpose)

No point in clicking on the buttons, they don't lead anywhere
