How can I visually identify which board revision I have?

This question asks about using /proc/cpuinfo to identify the revision of the board I have. Are there any visual characteristics that differentiate between the different board revisions?

How does a program check whether it's running on a 512MB RPi?

Do the 512MB RPI's have a different board revision? ie, can you just look at the revision in /proc/cpuinfo to determine if you have a 512MB RPi? Otherwise what's the easiest way to check?
