Abstract
Universal formalism of QFT operates on abstract entities like point particles, not asking about their spatial structures, dynamics behind processes like photon production. Topological soltions, vacuum analogues of Abrikosov vortices, bring hope to understand field configurations behind Feynman diagrams, by the way explaining many fundamental assumptions, like spin, charge or strangeness quantization by constructing them as topological charges. Skyrme has made popular this kind of approach to mesons and baryons, while perfect situation would be a single field which family of topological solitons corresponds to our whole particle menagerie and their behavior. Here is discussed such unifying all interactions simple attempt - practically by just expanding field of unit vectors of Faber's electron model, which can be seen as reformulation of electromagnetic field to enforce charge quantization, by a single degree of freedom corresponding to quantum phase: of rotations around this direction (vacuum dynamics changes from $S^2$ to SO(3)). This simple model also suggests intuitive answers to many fundamental questions of physics.
