I like #1 best but #2 is also very interesting. The first ideas [for #2] that come to my mind are the inside of a volcano crater or a explosion crater. This is the result of the 10mm lens, of course.
Thank you much Francis. it's a funny and inspiring play.....as with a macro, or a micro, or a super tele, with this extreme wide we can find perspectives/perceptions not easily viewable. some days ago I read (again) a tale of Jorge Louis Borges, "El Aleph".....this kind of glass seems to this Aleph, a sort of collection of all we can see and beyond.
All the best,
