thanks for advice, the 2 ornaments are ocean coral thats been laquered, i have many ornaments not in there, a sunken ship, a fake coral cave reef and more, think i'll experiment then post an update
also for anyone that loves fish and ocean stuff, get digital aquarium from www.a-moray.com
they have a dvd thats 54 minutes of great underwater ocean footage showing tons of exatic fish, coral...etc
i use dreamrender from www.dreamrender.com which can be used to creat animated desktop background and also plays video as a desktop, i used my video capture card connected to my dvd player to record it on my hard drive, then select the recording in dreamrender which plays the video as a desktop background....now you have 54 minutes of great underwater footage on your computer desktop instead of those boring wallpapers
