  The light-front representation of quantum chromodynamics provides a
frame-independent, quantum-mechanical representation of hadrons at the
amplitude level, capable of encoding their multi-quark, hidden-color and gluon
momentum, helicity, and flavor correlations in the form of universal
process-independent hadron wavefunctions. The universality and
frame-independence of the LCWF's thus allow a profound connection between
diffractive dissociation, hard scattering exclusive processes such as elastic
form factors, two-photon reactions, and heavy hadron decays. In this concluding
talk of the ECT* International Conference On Light-Cone Physics: Particles And
Strings (Trento 2001), I review recent calculations and new applications of
light-front wavefunctions in QCD and other theories. I also review the
distinction between the structure functions measured in deep inelastic lepton
scattering and the quark distributions determined from light-front
wavefunctions.
