What really gets me is just how far it is between the mainland and the islands. That 5-hour flight from CA across nothing but water can be overwhelming. One might think Hawaii is a lonely place way out there in the middle of the Pacific, but when you get there, it's a busy, thriving state, and Honolulu itself is quite a city.
Here are two beach webcams (operated by the city of Honolulu) that I love to look at. I've had friends stand in front of the cams and wave to me as we speak via cell phone.

One of the cams doesn't seem to be working today, but it usually does. Both cams have some pretty good background music.
