I'm not sure if this is what you are hoping for but my comic, Beautiful Lies, is obscure in the sense that it's a psychological with little dialogue. It requires a bit of thinking to understand what is going on/ why this is happening.
If you meant obscure as in no one knows about it, then ehm...well not that many people know it but it's not a complete mystery.

Just a sample of the obscureness I think. I plan to redo these pages in the future.
