It is a good point, and it works in more obvious ways in the music scene. One band/artist will be wildly successful with their original content, and then suddenly their are 100s of copycats, most of whom only claim to be influenced by the original artist, but then there are some who are so blind that they can not even admit this to themselves! It is one thing to reproduce an attractive element in a scape, but it is another thing entirely to reproduce a map or pattern of elements that has already been done to death. If they merely reflect what's already available in nature? That is perfectly fine and admirable, and you cannot make too many similar scapes of this fashion. If those elements are reproducing something that already looked gimmicky or artificial and isn't readily seen in nature? Then it is not so much a "Nature Aquarium" as much as a "Scaper Aquarium". Personally, one things I've always appreciated about the Amano cannon is their ability to represent what they are actually looking at when the visit a river or hike in the mountains, but on a much smaller scale. I just spent a lot of time in Yosemite this past weekend, and there is endless metaphor, endless inspiration, and all at your fingertips. To ignore that kind offering for the likes of copying a picture you saw on the internet just seems lazy.
