  We construct moduli spaces of representations of quivers over arbitrary
schemes and show how moduli spaces of pointed curves of genus zero like the
Grothendieck-Knudsen moduli spaces $\overline{M}_{0,n}$ and the Losev-Manin
moduli spaces $\overline{L}_n$ can be interpreted as inverse limits of moduli
spaces of representations of certain bipartite quivers. We also investigate the
case of more general Hassett moduli spaces $\overline{M}_{0,a}$ of weighted
pointed stable curves of genus zero.
