  In the light of the recent Lin, Lunin, Maldacena (LLM) results we investigate
1/2-BPS geometries in minimal (and next-to minimal) supergravity in D=6
dimensions. In the case of minimal supergravity, solutions are given by
fibrations of a two-torus T^2 specified by two harmonic functions. For a
rectangular torus the two functions are related by a non-linear equation with
rare solutions: AdS_3x S^3, the pp-wave and the multi-center string.
``Bubbling'', i.e. superpositions of droplets, is accommodated by allowing the
complex structure of the T^2 to vary over the base. The analysis is repeated in
the presence of a tensor multiplet and similar conclusions are reached with
generic solutions describing D1D5 (or their dual fundamental string-momentum)
systems. In this framework, the profile of the dual fundamental string-momentum
system is identified with the boundaries of the droplets in a two-dimensional
plane.
