Hey Jim,
Everything is looking great so far
. I have one suggestion that would be amazing. In the cave, I always feel it is missing something and then at The Rusty Pelican restaurant they had a saltwater tank very similar to your new MA3 screensaver with a cave as well. inside the cave popped out an Eal to my surprise.. I know that the cave in yours is small and has a back to it that is fully visible. However if you re-design it in such a way where an Eal head could pop out every now and then or simply be on screen at all times would be amazing. I love the featherduster as well.. Very nice work Jim.
