Recently, Nokia held a big light show on the Millbank tower by turning the tower into a canvas where they showed awesome 4D animations! They did this to announce the release of their first Windows based smart phone, Nokia Lumia 800. But, they forgot something… A part of that building belongs to Ubuntu! Its their headquarters!
If some one come to your house, you must greet them and say hello! So, Ubuntu found a quick unique way to say hello to their neighbours! But, they only had few minutes and one floor to plan it!
