  We report on the first steps in the development of a small-size muon
telescope based on glass Resistive Plate Chambers with small active area
($16\times 16~{\rm cm}^2$). The long-term goal of this project is to focus on
applications of muography where the telescope may have to be operated
underground and/or inside small rooms, and in challenging logistic situations.
Driving principles in our design are therefore compact size, light weight, gas
tightness, and robustness. The first data-taking experiences have been
encouraging, and we elaborate on the lessons learnt and future directions for
development.
