SUMS: Robert Tang -- Roy Orbifold: Shaping Music

My talk will be on geometric spaces called orbifolds.  These are, roughly speaking,
smooth objects with cone points or folded edges.  I will use these to depict how various
classes of objects, such as triangles or musical chords, can be given a natural
geometry.  This will be a very hands-on talk with plenty of models, pictures and maybe
even sounds! There will also be free (edible) models of orbifolds with corner reflectors
at the half time interlude for all audience members.
