The various forms of handouts in university studies cover a large spectrum from complete reference texts to cheat-sheets. We present our experiences in very compact handouts, "pico" handouts, that we call "picopoly" in French. We have been using them consistently in various learning formats, from full semester modules to conferences, and in very different domains, from epistemology to algorithmics. The initial aim was to clarify for the students the expected inputs, i.e. prerequisites and context knowledge, and outputs, i.e. learning outcomes. Very compact, they only give an overview of these inputs and outputs, but they are intended as maps of territories that will be explored during the learning experience.
