I found the first short, Vertical Roll, to be the most intruiging of all the shorts we viewed.  It was painful to watch and I did have to close my eyes here and there to stop from feeling too dizzy. But this was a really interesting and effective technique.  It was almost as if the viewer had to embody the shock, disjointedness and tortuous repetition that the artist did in her own experience.  It reminded me of Artaud's Theater of Cruelty.
