Hi Brandon, welcome to Physics.SE! It's very unclear what you're talking about, and what you're asking. Can you give us some more information? – DilithiumMatrix Apr 21 '13 at 3:26
To expand on what zhermes said, this is a site for specific, answerable questions. If you're just looking to invite a discussion, this isn't the place to do it, as stated in our FAQ. – David Z Apr 21 '13 at 4:01
Brandon, I've edited the question to make it follow the site's rules a bit better. Please feel free to undo this or re-edit the question if you don't like the new version. – Nathaniel Apr 21 '13 at 5:11
With Nathaniel's edits this looks like an interesting question. Brandon, if you Google for "swash sorting" you'll get lots of relevant hits. – John Rennie Apr 21 '13 at 6:16
Thanks john...swash sorting is what I'm talking about. The beach near my house is full of shark teeth so predicting whether they will be on the beach or underwater is my focus. – Brandon Apr 21 '13 at 11:20
