People waving at their computers or devices will no longer be a peculiar scenario in the very near future, mostly thanks to Mycestro. A wearable, ergonomic 3D mouse, slip Mycestro on your finger and use gestures to control your cursor. Especially useful if you find yourself lacking ample horizontal surface to operate a conventional mouse, it wirelessly connects to your computer, tablet or other device allowing you to control the cursor from up to 30 feet away.
