A notch up from the standing desk, this human hamster wheel allows you to multitask. Many people grow concerned about staying stationary at their desks, but this hamster wheel standing desk allows you to prioritize your daily exercise while also getting work done. Instructions to build your own are available on Instructables.
This human hamster wheel gives you everything you could ask for in a desk, save for perhaps a water bottle. This productivity-maximizing invention is a collaborative project from Pier 9 Artist in Residence Robb Godshaw and Instructables developer Will Doenlen. While this particular contraption appears to be placed in a shared office, your own version would work well at home as not to disturb others.
