Spin foam vertex amplitudes are the key ingredient of spin foam models for quantum gravity. These fall into the realm of discretized path integral. and can be seen as generalized lattice gauge theories. They can be seen as an attempt at a 4-dimensional generalization of the Ponzano-Regge model for 3d quantum gravity. https://www.roneverhart.com/Funko-Vinyl-Gold-Premium-Figure-NBA-Lakers-LeBron-James-City-Edition-Chase/
