i don't know about anyone else but i really like to look at refugiums. i was at ping's house this weekend and was impressed with how many refugiums he had going. it is interesting to see what kind and how much life will grow. the fuge for my tank is a 40gl tub with 4 large mangroves and many smaller seedlings along with multiple types of calurpa and cheato. the tub sits next to the tank and is open for display. lets see some pictures of refugium set up that you have (ping), maybe it will give others some ideas of how to set up theirs.
