Move your mouse around; press the arrow keys to make the apple come closer or go further from you.
Credits to @novice27b for the original project! I implemented a (pretend) Z-axis for fun - I wondered if it might make it more so the cameras were tracking "you" instead of the mouse. I think it sort-of worked :P There's also a script in there for a camera flashing thing. I was going to make it so movement would make them flash (and periodically they'd all flash in consecution). I only got to implementing the first idea, and it didn't turn out as well as I like, but if you see inside you can re-attach that script (at the end of the repeat loop) and you can see what I tried there. :P
