Emitters project coloured beams; the player rotates mirrors to bend each beam into a receiver that requires that colour. Beams are drawn with particles, client-side.

A vault whose door opens once red and blue beams reach their own crystals. Setting a mirror's rotatable to false fixes part of the path and turns the room into a real routing problem.
