In order to meditate and refresh your mind in a playful mood, the best thing you could have is this Mind-Controlled Helicopter by Puzzlebox Orbit. Just like the name sounds, it is an helicopter you can control directly from your mind. All you need to do is focus your level of concentration on this one device and let the EEG headset record your mind readings and direct the helicopter into flying by following your instructions. For positive feedbacks on mind development, you can use the corresponding Android or iOS app and let your mind relax after undergoing hours of strenuous work. Meditation has now gone tech-savvy which is ofcourse a good thing for all of us.
