It was a tool in RTB for Blockland Alpha. It compensated for the lagginess of high brick builds in the alpha by allowing people to stretch, deform, move, and rotate bricks. It is not possible to recreate in Blockland for a few reasons, namely that bricks can no longer be rescaled, nor can they be rotated in a direction other than the four cardinal ones. Additionally, largely stretched bricks looked pretty ugly with the textures stretching.
