Mario's rig: Mario's rig as an instrument of the tennis pedagogy
allowing him to contribute via making the annual E.T.A. fundraising documentary cartridge, videotaping students’ strokes and occasionally from over the railing of Schtitt’s supervisory transom the occasional challenge-match—the taping’s become part of the pro-instruction package detailed in the E.T.A. catalogue
Context
Mario's whole apparatus-body gets absorbed into the academy's coaching machinery. The head-mount Bolex, the police-lock buttress, the whole rig lets him do "videotaping students' strokes... from over the railing of Schtitt's supervisory transom," and "the taping's become part of the pro-instruction package detailed in the E.T.A. catalogue." His engineered body has been made an instrument of stroke-analysis — the institution has a use for it, folding the deformed son into the pedagogy as the eye that records the players' mechanics for review. The body-as-equipment lands here as equipment of the tennis regimen specifically. (The police-lock/block-feet mechanics are d-d's blockquotes — cross-ref, no duplication.)
