A few days ago, the oldest son decided to share what he and his younger brother had been busy doing: the Akinator. It is a very entertaining and potentially useful "character finder" as the AI asks questions until it "knows" enough to quess who the person using the Akinator is thinking of.

The Akinator was developed by three French programmers back in 2007, became popular in the next few years and today it is available both online (free) and as a smartphone app (which you'd have to pay a small sum for). Try it out if you haven't done so before!
