Something to look at Shannon has a degenerative hip condition and has developed this way of dancing with crutches.Here's what he says about his movement:

Through dancing I have created an entire classification of movement that is technically specific while culturally a hybrid and unique unto me ... in a way I have invented a new form, profoundly different from anything you may have seen ... this invention is rooted in the hiphop/skateboard tradition of street improvisation yet has a formal timeless quality beyond the boundaries of its roots ... I dance in the street when I walk in the street ... the whole street watches me walk ... walk a block with me ... you will see.
