"Coloured fantastacks"

I will give a very light, example-oriented introduction to coloured fantastacks, which are introduced in my paper “Horospherical stacks and stacky coloured fans” (arXiv 2305.01571). These are a particular class of horospherical stacks which arise from a hands-on combinatorial construction. Knowledge of stacks will not be required as an audience member because the speaker does not have it either.
