• Create a page with some images, a button and either text or images to act as a counter on it
• When the button is clicked, use ActionScript to go to the same frame but increase the counter in some way
• A variable will be required to count how many times that frame has been entered. Either display the value of this variable directly, or use it to change the size, colour, shape etc of an image, or group of images.

I didn't actually do this one I don't think, but will come back to it!
