We discuss nonstandard continuum quantum field theories in 2+1 dimensions. They exhibit exotic global symmetries, a subtle spectrum of charged excitations, and dualities similar to systems 1+1 These models represent the low-energy limits certain known lattice systems. One key aspect these is important role played by discontinuous configurations. In two companion papers, we will present 3+1-dimensional versions particular, some fractons.
