  We find new BPS solutions to the nonabelian theory on a world-volume of
parallel D1-branes. Our solutions describe two parallel, separated bundles of N
D1-branes expanding out to form a single orthogonal D3-brane. This
configuration corresponds to two charge N magnetic monopoles in the
world-volume of a single D3-brane, deforming the D3-brane into two parallel
spikes. We obtain the emergent surface corresponding to our nonabelian D1-brane
configuration and demonstrate, at finite N, a surprisingly accurate agreement
with the shape of the D3-brane world-volume as obtained from the abelian
Born-Infeld action. Our solution provides an explicit realization of topology
change in noncommutative geometry at finite N.
