Cool name eh? I looked up periodic orbits - all to do with chaos theory and gaaaaaaah what they said wasn't written in English! Topological entropy, chaotic attractors, bifurcation order, phase space partitions Faaaaaaaaaaaaaark! Anyway I still like the name even if I don't understand any of it. Distressed, aged and sealed nickel
Boulder opal still in the matrix. Some show flashes of colour.
Amethyst, rhyolite, quartz crystals, iron pyrite, amber and green quartz? and a chunk of some other green stuff. Have no idea what I am going to do with them, but my muse just had to have them.
