Darumouse = Daruma + Mouse. Daruma being a round Japanese wish doll with no arms and legs, modelled after Bodhidharma and often used as a good-luck charm.
The larger darumouse has 6 buttons (left, right clicks; scroll up, down; forward, backward) and the smaller one has 4 (left, right clicks; scroll up, down). Darumouse can be operated in the air.
Users can also control the cursor by just tilting their darmouse.
The product is already available for purchase in Japan (where else?) But what’s interesting is that the manufacturer claims they can turn anything into a mouse providing that the physical shape/size allows it. They are even planning to sell made-to-order mouses: customer would send their favorite physical object to them and they would turn it into a mouse. The company would sell only the internal electronic components.
