DATUM

Motion

Bench

Small things, built properly. A datum is a fixed point everything else is measured against, so the things that end up here tend to be about measuring.

Stack

One button

A course slides across. Drop it on the one below. Whatever hangs over the edge is cut off, so every sloppy drop makes the next one harder, and a dead centre landing hands some width back.

Motion is set to reduced, and this is the one thing on the site that cannot honour it: the course has to move for there to be anything to time. Everything else is off. The offcut vanishes instead of falling and the view cuts instead of easing.
