Amplituhedra in the Grassmannian of Lines in 3-space

I will present an ongoing work in progress with Simon Telen where we study amplituhedra contained in the Grassmannian Gr(2,4) of lines in projective 3-space. We are particularly interested in geometric descriptions, the algebraic boundary, and the adjoint which should correspond to the numerator of the canonical form in the sense of positive geometry.
