Abstract: 
The motivation and mechanism for producing an open universe by
nucleating a bubble (Bucher, Goldhaber and Turok) will be reviewed.
Current results for and understandings of density perturbations will
be summarized.  Some constraints on the resulting power spectrum from
the data, which can be used to guide model building, will
be described.
