3D pedestrian simulation game developed for web browsers using Three.js. The red-shirted agent is controlled by human key inputs or swipes on the touchscreen. I am attempting to make other agents walk more intelligently.

toio cubes seem to be just cute toys but are also full-scale programmable robots.

Simply combining the two example codes 'chase' and 'keyboard-control', a toio core cube can chase another cube controlled with a keyboard. The two cubes are connected through Bluetooth to my Mac running Node.js.

Spreading all the additional paper mats sold at switch-science.com my toio cubes have 12x space to move around.

One more toio core cube joined. The first cube is controlled with a keyboard. Other cubes chase the cube in front of them.
