During the last Netguru team dinner a friend showed me a neat feature of his fancy Samsung device - Gesture Control to Take a Selfie (detecting hand to take a selfie). For some time now I’ve been interested in machine learning and I thought of implementing this myself.

In 10th century Harald Gormsson, the king of Denmark and Norway united most of Jutland and Zealand under his reign. To this day we are celebrating his achievements by using one of the handiest communication technologies ever created, named after his nickname.
