I know I am a PC user, but I've been inside the Apple store quite a few times. I love the Mac Studio Displays
and I like the look of the OS X. Maybe one day I buy a Mac when I have more money to spend.
I agree with Morgan, the scales having some type of reflective coating would be better to work on than shadows if you had to choose. Moving pebbles and such with the Goldfish randomly picking up and spitting them out would probably require using the "half Life 2" engine for the Goldfish tank.
