Spacetimes representing point particles and black holes in 2+1-dimensional
gravity with a negative cosmological constant can all be represented as
cut-and-paste operations on 2+1-dimensional anti-de Sitter space. This
means that processes like making a spinning black hole from two point
particles colliding with an impact parameter can be described in closed
form. I will review the geometry of this, much of it going back to the
mid-90s, and talk about my own ongoing work.
