I will discuss a construction of Coulomb branches in the gauged linear sigma model
for a quaternionic representation of a compact group G. This modifies the original
construction of Braverman, Finkelberg and Nakajima with some topological twists 
dating to the early days of K-theory. Natural and intriguing speculations
about a 3D firks theory and about categorification to 4D will also be mentioned.
