these next few things have a sort of "under the sea" feel to them...
buttons and glue:
(pretty incredible to see in real life... looks just like a coral reef and the type of buttons both clear and opaque play tricks on your eyes and sort of blur your vision.. really cool
)
mylar:
(the play of light on the mylar is VERY cool in person)
fishing line:
