We present exact massless solutions of the boundstate integral equations in the large N limit. These massless states have constant wavefunctions in momentum space and are therefore fundamental excitations of the theory.8 pages Latex, Invited talk at ``New Non-perturbative Methods and Quantization on the Light-Cone", Les Houches France 24 Feb. - 7 March 1997High Energy Physics - Theorytext
