Abstract
There exists an infinite-parameter set of 'neighbours' of Einstein's e quations (at least if complex metrics are admitted). New results repor ted here include exact solutions with self-dual Riemann tensor for a l arge class of these models, partial results concerning matter coupling s, and a discussion of metrical signatures in the real case.
