interesting forms, kind of reminds me of the fusion work I messed with a bit, or Elliot Pujol's crazy constructs.
Casting metal in place is interesting, I'm guessing you used a simple medium melt wax given the thinness of the spindle and the chunkiness of the rest of the forms. Was this a gravity pour, centrifugal, or vacuum cast?
these are absolutely incredible. for some reason i imagine sitting in a frigid, dimly-lit room listening to Emilie Autumn while drinking from one of these. no clue why i thought Emilie Autumn, but i'm sure they'd be lovely while listening to anything.
