I suppose you could pseudo-reef in Hawaii:
1. Find an attractive stand of coral just off-shore of your house. If you don't live on the beach, get as close as you can.
2. Go diving with a hammer and a stick of epoxy. Transplant any nearby corals that you don't like to another stand. Snorkel around and bring frags of any cool corals you find back to "your" reef.
3. Go diving every couple of days with a packet of fish food, and you'll never lack for beautiful fishes. Once they learn where they're being fed, they tend to hang around. With enough ornamentals sticking close to your feeding zone, you might even attract some sharks to "your" reef.
4. Set up a wireless webcam in an airtight housing a few feet away, and have a dedicated monitor in your living room showing the live feed 24/7. You might need a wireless router at the end of a looong cord to pick up the signal, though.
No need for a skimmer, flow that can't be matched in a glass box, free lighting, cool hitchhikers arriving all the time. What's not to like?
You'd probably get in trouble for damaging corals if you tried to do the aquascaping described above, but it's still a pleasant daydream.
