Reader reactions to a provocative visualisation of the border wall proposed by Donald Trump lead this week's comments update.

Against the wall: Estudio 3.14 has responded to Trump's controversial plan to build a wall along the Mexico-USA border, visualising a pink structure inspired by Mexican architect Luis Barragán.

Rock-a-bye baby: a self-rocking robotic crib designed by Yves Behar to aid exhausted parents proved controversial this week, as readers questioned whether it could replace the real thing.
