The Globus Mobile is a complete office workstation and chair hidden in
a large ball. The concept by designer Michiel van der Kley can be moved
to any place using its hidden wheels. When you want to work, you just
swivel it open and bingo: you can slot in a laptop, perch on the padded
chair and think up as many chicken-and-egg or ping-pong ball jokes as
you like.
