Rodrigo Alonso / Susanne Weigand

We've all seen keyboard rings before but here's one that recognizes the most indispensable keys of all: Ctrl+Z. Chilean designer Rodrigo Alonso comes to the rescue of anyone who's ever wished s/he could "undo."

Visit his site for more modern jewellery and product design, such as this fun wind-up "toy" ring.
